DATASHEET RAA210825 FN9349 Rev.1.00 Feb 8, 2019 Pin-Configurable 25A DC/DC Power Module with PMBus Interface The RAA210825 is a pin-strap configurable 25A step-down PMBus-compliant DC/DC power supply module that integrates a digital PWM controller, synchronous MOSFETs, power inductor, and passive components. Only input and output capacitors are needed to finish the design. Because of its thermally-enhanced HDA packaging technology, the module can deliver up to 25A of continuous output current without the need for airflow or additional heat sinking. The RAA210825 simplifies configuration and control of Renesas digital power technology while offering an upgrade path to full PMBus configuration through the pin-compatible ISL8277M. The RAA210825 uses ChargeModeTM control architecture, which responds to a transient load within a single switching cycle. The RAA210825 comes with a preprogrammed configuration for operating in a pin-strap mode. Output voltage, switching frequency, input UVLO, soft-start/stop delay and ramp times, and the device SMBus address can be programmed with external pin-strap resistors. A standard PMBus interface addresses fault management, in addition to real-time full telemetry and point-of-load monitoring. The RAA210825 is available in a 41 Ld compact 17mmx19mm HDA module with very low profile height of 3.6mm, suitable for automated assembly by standard surface mount equipment. The RAA210825 is RoHS compliant by exemption.

CIN bulk capacitor is optional only for energy buffer from the long input power supply cable. 7. ASCR gain and residual are selected to ensure that the phase margin is higher than 60 at ambient room temperature (+25C). 8. Peak-to-peak voltage deviation is measured under 0%-50% load transient and slew rate = 15A/s. 9. Frequency is selected to achieve best efficiency at full load. Higher frequency can be selected because less output capacitance is required to meet the transient response specification. Table 2.

Functional Description Functional Description 4.1 SMBus Communications The RAA210825 provides an SMBus digital interface that enables the user to configure the module operation in addition to monitoring the input and output parameters. The RAA210825 can be used with any SMBus host device. In addition, the module is compatible with PMBus Power System Management Protocol Specification Parts I & II version 1.2. The RAA210825 accepts most standard PMBus commands. Renesas recommends tying the enable pin to SGND when PMBus commands are issued. The SMBus device address is the only parameter that must be set by external pins. 4.2 Output Voltage Selection The output voltage may be set to a voltage between 0.6V and 5V provided that the input voltage is higher than the desired output voltage by an amount sufficient to maintain regulation. The VSET pin sets the output voltage to any values between 0.6V and 5V, as shown in Table 5. The RSET resistor is placed between the VSET pin and SGND. A standard 1% resistor is recommended. Table 5.

FN9349 Rev.1.00 Feb 8, 2019 Page 20 of 56 RAA210825 4.3 4. Functional Description Soft-Start Delay and Ramp Times The RAA210825 follows an internal start-up procedure after power is applied to the VDD pin. The module requires approximately 60ms to 70ms to check for specific values stored in its internal memory and programmed by pin-strap resistors. When this process is complete, the device is ready to accept commands from the PMBus interface and the module is ready to be enabled. If the module is synchronizing to an external clock source, the clock frequency must be stable prior to asserting the EN pin. It may be necessary to set a delay from when an enable signal is received until the output voltage starts to ramp to its target value. In addition, the designer may wish to precisely set the time required for VOUT to ramp to its target value after the delay period has expired. These features can be used as part of an overall inrush current management strategy or to precisely control how fast a load IC is turned on. The RAA210825 gives the system designer several options for precisely and independently controlling both the delay and ramp time periods. The soft-start delay period begins when the EN pin is asserted and ends when the delay time expires. The soft-start delay (TON_DELAY) and ramp-up time (TON_RISE) can be set to custom values with pin-strap resistors or PMBus. When the delay time is set to 0ms, the device begins its ramp-up after the internal circuitry has initialized (approximately 2ms). When the soft-start ramp period is set to 0ms, the output ramps up as quickly as the output load capacitance and loop settings allow. In general, set the soft-start ramp to a value greater than 500s to prevent inadvertent fault conditions due to excessive inrush current. Similar to the soft-start delay and ramp-up time, the delay (TOFF_DELAY) and ramp-down time (TOFF_FALL) for soft-stop/off can be set to custom values with pin-strap resistors or PMBus. In addition, the module can be configured as "immediate off" with the command ON_OFF_CONFIG, such that the internal MOSFETs are turned off immediately after the delay time expires. The SS/UVLO pin can program the soft-start/stop delay time and ramp time to some typical values as shown in Table 6. A standard 1% resistor is required. Table 6.

By default, the PG pin asserts if the output is within 10% of the target voltage. These limits and the polarity of the pin may be changed with PMBus command POWER_GOOD_ON. A PG delay period is defined as the time from when all conditions within the RAA210825 for asserting PG are met to when the PG pin is actually asserted. This feature is commonly used instead of using an external reset controller to control external digital logic. A fixed PG delay of 4ms is programmed for RAA210825. 4.5 Switching Frequency and PLL The device's switching frequency is configurable from 296kHz to 1067kHz using the pin-strap method as shown in Table 7, or by using a PMBus command FREQUENCY_SWITCH.

Functional Description The RAA210825 incorporates an internal Phase-Locked Loop (PLL) to clock the internal circuitry. The PLL can also be driven by an external clock source connected to the SYNC pin. Set this configuration by connecting a resistor to the CFG pin. If the clock source is internal, the internal frequency is set according to the SYNC pin resistor settings. If the clock source is external, the internal frequency is set according to the resistor connected to the CFG pin as shown in Table 8. The incoming clock signal must be stable when the enable pin is asserted. The external clock signal must not vary more than 10% from its initial value and should have a minimum pulse width of 150ns. Note: If the pin-strap method is used, a standard 1% resistor is required. Table 8.

A standard 1% resistor is required. The RAA210825 uses the ChargeMode control algorithm that responds to output current changes within a single PWM switching cycle, achieving a smaller total output voltage variation with less output capacitance than traditional PWM controllers.

The UVLO threshold (VUVLO) can be set between 4.18V and 16V using the pin-strap method as shown in Table 10, or by using a PMBus command VIN_UV_FAULT_LIMIT. A standard 1% resistor is required. The module shuts down immediately when the UVLO threshold is reached. The fault needs to be cleared for the module to restart. Table 10.

A hardware comparator compares the actual output voltage (seen at the VSEN+ and VSEN- pins) to a threshold set to 15% higher than the target output voltage. The fault threshold can be programmed to a desired level with PMBus command VOUT_OV_FAULT_LIMIT. If the VSEN+ voltage exceeds this threshold, the module initiates an immediate shutdown without retry. Internal to the module, a 332 resistor is populated from VOUT to VSEN+ to protect the device from overvoltage conditions in case of an open at VSENSE pin and differential remote sense traces due to assembly error. As long as differential remote sense traces have low resistance, VOUT regulation accuracy is not sacrificed. 4.10 Output Prebias Protection An output prebias condition exists when an externally applied voltage is present on a power supply's output before the power supply's control IC is enabled. Certain applications require that the converter not be allowed to sink current during start-up if a prebias condition exists at the output. The RAA210825 provides prebias protection by sampling the output voltage prior to initiating an output ramp. If a prebias voltage lower than the target voltage exists after the preconfigured delay period has expired, the target voltage is set to match the existing prebias voltage, and both drivers are enabled. The output voltage is then ramped to the final regulation value at the preconfigured ramp rate. The actual time the output takes to ramp from the prebias voltage to the target voltage varies, depending on the prebias voltage, however, the total time elapsed from when the delay period expires and when the output reaches its target value matches the preconfigured ramp time (see Figure 26 on page 27). If a prebias voltage is higher than the target voltage after the preconfigured delay period has expired, the target voltage is set to match the existing prebias voltage, and both drivers are enabled with a PWM duty cycle that would ideally create the prebias voltage. When the preconfigured soft-start ramp period has expired, the PG pin is asserted (assuming the prebias voltage is not higher than the overvoltage limit). The PWM then adjusts its duty cycle to match the original target voltage, and the output ramps down to the preconfigured output voltage. If a prebias voltage is higher than the overvoltage limit, the device does not initiate a turn-on sequence and declares an overvoltage fault condition.

Output Responses to Prebias Voltages 4.11 Output Overcurrent Protection The RAA210825 can protect the power supply from damage if the output is shorted to ground or if an overload condition is imposed on the output. Average output overcurrent fault threshold can be programmed with PMBus command IOUT_OC_FAULT_LIMIT. The module automatically programs the peak inductor current fault threshold by reading real-time input voltage, switching frequency, and VOUT_COMMAND to calculate the inductor ripple current. The default response from an overcurrent fault is an immediate shutdown with a continuous retry of 70ms delay. 4.12 Thermal Overload Protection The RAA210825 includes a thermal sensor that continuously measures the internal temperature of the module and shuts down the controller when the temperature exceeds the preset limit. The default temperature limit is set to +115C in the factory, but can be changed with PMBus command OT_FAULT_LIMIT. The response from an over-temperature fault is an immediate shutdown without retry. 4.13 Phase Spreading When multiple point-of-load converters share a common DC input supply, adjust the clock phase offset of each device, such that not all devices start to switch simultaneously. Setting each converter to start its switching cycle at a different point in time can dramatically reduce input capacitance requirements and efficiency losses. Because the peak current drawn from the input supply is effectively spread out over a period of time, the peak current drawn at any given moment is reduced, and the power losses proportional to the IRMS2 are reduced dramatically. To enable phase spreading, all converters must be synchronized to the same switching clock. The phase offset between devices is determined from the lower four bits of the SMBus address of each interleaved device. The phase offset of each device can set to any value between 0 and 360 in 22.5 increments. This functionality can also be accessed using the PMBus command INTERLEAVE.

FN9349 Rev.1.00 Feb 8, 2019 Page 28 of 56 RAA210825 5. 5. PCB Layout Guidelines PCB Layout Guidelines To achieve stable operation, low losses, and good thermal performance, some layout considerations are necessary. * For VDD > 6V, the recommended PCB layout is shown in Figure 27. Leave V25, VDDC, VR5, and VR6 as "No Connect (NC)". * For 5.5V VDD 6V, connect the VDDC pin to the VR6 pin. For 4.5 VDD < 5.5V, connect the VDDC pin to the VR6 and VR5 pin. An RC filter is required at the input of the VDRVIN pin if input supply is shared with the VIN pin. * Establish a separate SGND plane and PGND plane, then connect the SGND to the PGND plane as shown in Figure 28 in the middle layer. For making connections between SGND/PGND on the top layer and other layers, use multiple vias for each pin to connect to the inner SGND/PGND layer. Do not connect SGND directly to PGND on a top layer. Connecting SGND directly to PGND without establishing an SGND plane bypasses the decoupling capacitor at internal reference supplies, making the controller susceptible to noise. * Place ceramic capacitors between VIN and PGND, VOUT and PGND, and the bypass capacitors between VDD and the ground plane, as close to the module as possible to minimize high frequency noise. * Use large copper areas for power path (VIN, PGND, VOUT) to minimize conduction loss and thermal stress. Also, use multiple vias to connect the power planes in different layers. Extra ceramic capacitors at VIN and VOUT can be placed on the bottom layer under VIN and VOUT pads when multiple vias are used for connecting copper pads on top and bottom layers. * Connect differential remote-sensing traces to the regulation point to achieve a tight output voltage regulation. Route a trace from and VSEN+ to the point-of-load where the tight output voltage is desired. Avoid routing any sensitive signal traces, such as the VSENSE signal near VSWH pads.

External airflow might be required to keep module heat at desired level. For applications where switching noise is less critical, an excellent thermal performance can be achieved in the RAA210825 module by increasing copper mass attached to VSWH pad. To increase copper mass on the VSWH node, create copper islands in the middle and bottom layers under the VSWH pad and connect them to the top layer with multiple vias. Make sure to shield those copper islands with a PGND layer to avoid any interference to noise sensitive signals. PGND VCC NC VSWH PGND CVIN VOUT NC VIN PGND CVOUT Figure 27.

The derating curves are derived from the maximum power allowed while maintaining the temperature below the maximum junction temperature of +125C. In actual application, consider other heat sources and design margins. 5.2 Package Description The RAA210825 uses the High Density Array (HDA) no-lead package. This kind of package has advantages, such as good thermal and electrical conductivity, low weight, and small size. The HDA package is applicable for surface mounting technology and is being more readily used in the industry. The RAA210825 contains several types of devices, including resistors, capacitors, inductors, and control ICs. The RAA210825 is a copper lead-frame based package with exposed copper thermal pads, which have good electrical and thermal conductivity. The copper lead frame and multi-component assembly is overmolded with polymer mold compound to protect these devices. The package outline, a typical PCB land pattern design, and a typical stencil opening edge position are shown in the "Package Outline Drawing" section starting on page 49. The module has a small size of 17mmx19mmx3.6mm. Figure 29 on page 31 shows typical reflow profile parameters. These guidelines are general design rules. Users can modify parameters according to their application. 5.3 PCB Layout Pattern Design The bottom of the RAA210825 is a lead-frame footprint, which is attached to the PCB by surface mounting process. The PCB land pattern is shown in the "Package Outline Drawing" section starting on page 49. The PCB layout pattern is an array of solder mask defined PCB lands which align with the perimeters of the HDA exposed pads and I/O termination dimensions. The thermal lands on the PCB layout also feature an array of solder mask defined lands and should match 1:1 with the package exposed die pad perimeters. The exposed solder mask defined PCB land area should be 50-80% of the available module I/O area. FN9349 Rev.1.00 Feb 8, 2019 Page 30 of 56 RAA210825 5.4 5. PCB Layout Guidelines Thermal Vias A grid of 1.0mm to 1.2mm pitch thermal vias, which drops down and connects to buried copper plane(s), should be placed under the thermal land. The vias should be about 0.3mm to 0.33mm in diameter with the barrel plated to about 1.0 ounce copper. Although adding more vias (by decreasing via pitch) improves the thermal performance, diminishing returns are seen as more and more vias are added. Simply use as many vias as practical for the thermal land size and that your board design rules allow. 5.5 Stencil Pattern Design Reflowed solder joints on the perimeter I/O lands should have about a 50m to 75m (2 mil to 3 mil) standoff height. The solder paste stencil design is the first step in developing optimized, reliable solder joints. The stencil aperture size to solder mask defined PCB land size ratio should typically be 1:1. The aperture width can be reduced slightly to help prevent solder bridging between adjacent I/O lands. A typical solder stencil pattern is shown in the "Package Outline Drawing" section starting on page 49. Consider the symmetry of the whole stencil pattern when designing its pads. A laser cut, stainless steel stencil with electropolished trapezoidal walls is recommended. Electropolishing "smooths" the aperture walls resulting in reduced surface friction and better paste release, which reduces voids. Using a Trapezoidal Section Aperture (TSA) also promotes paste release and forms a "brick like" paste deposit that assists in firm component placement. A 0.1mm to 0.15mm stencil thickness is recommended for this large pitch (1.3mm) HDA. 5.6 Reflow Parameters Due to the low mount height of the HDA, a "No Clean" Type 3 solder paste per ANSI/J-STD-005 is recommended. Nitrogen purge is also recommended during reflow. A system board reflow profile depends on the thermal mass of the entire populated board, thus it is not practical to define a specific soldering profile just for the HDA. The profile given in Figure 29 is provided as a guideline, to be customized for varying manufacturing practices and applications. . 300 Peak Temperature ~+245C; Typically 60s-150s Above +217C Keep Less than 30s within 5C of Peak Temp.

PMBus Command Summary PMBus Data Formats * Linear-11 (L11) - L11 data format uses 5-bit two's compliment exponent (N) and 11-bit two's compliment mantissa (Y) to represent real world decimal value (X). The relation between the real world decimal value (X), N and Y is: X = Y * 2N Data Byte High 7 6 5 4 3 2 1 0 Exponent (N) Data Byte Low 7 6 5 4 3 2 1 0 Mantissa (Y) * Linear-16 Unsigned (L16u) - The L16u data format uses a fixed exponent (hard-coded to N = -13h) and a 16-bit unsigned integer mantissa (Y) to represent real world decimal value (X). The relation between the real world decimal value (X), N and Y is: X = Y * 2-13 * Linear-16 Signed (L16s) - The L16s data format uses a fixed exponent (hard-coded to N = -13h) and a 16-bit two's compliment mantissa (Y) to represent real world decimal value (X). Relation between the real world decimal value (X), N, and Y is: X = Y * 2-13 * Bit Field (BIT) - An explanation of Bit Field is provided in PMBus on "PMBus Command Descriptions" on page 35. * Custom (CUS) - An explanation of custom data format is provided in PMBus "PMBus Command Descriptions" on page 35. A combination of Bit Field and integer are common type of custom data format. * ASCII (ASC) - A variable length string of text characters that uses the ASCII data format. 6.2 PMBus Use Guidelines The PMBus is a powerful tool for configuring devices for circuit performance optimization. When configuring a device in a circuit, the device should be disabled whenever most settings are changed with PMBus commands. Some exceptions to this recommendation are OPERATION, ON_OFF_CONFIG, CLEAR_FAULTS, VOUT_COMMAND, and ASCCR_CONFIG. Any command can be read while the device is enabled. Many commands do not take effect until after the device has been re-enabled, hence the recommendation that commands that change device settings are written while the device is disabled. In addition, there should be a 2ms delay between repeated READ commands sent to the same device. When sending any other command, a 5ms delay is recommended between repeated commands sent to the same device. Commands not listed in the PMBus command summary are not allowed for customer use, and are reserved for factory use only. Issuing reserved commands may result in unexpected operation FN9349 Rev.1.00 Feb 8, 2019 Page 34 of 56 RAA210825 7. 7.
