These modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated output voltage from 0.69Vdc to 5.5Vdc, programmable via an external resistor. Features include frequency synchronization, remote On/Off, adjustable output voltage, over current and temperature protection, power good and output voltage sequencing. The Ruggedized version (-D) is capable of operation up to 105C and withstand high levels of shock and vibration. The Tunable LoopTM, allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area. * UL is a registered trademark of Underwriters Laboratories, Inc.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 20 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability.

IIN x 100 % The 12V TLynxTM modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 F ceramic and 10 F ceramic capacitors at the output of the module. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 41 provides output ripple information for different external capacitance values at various Vo and for a full load current of 20A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. Optimal performance of the module can be achieved by using the Tunable LoopTM (c)2017 General Electric Corporation. All rights reserved.

Two On/Off logic options are available. In the Positive Logic On/Off option, (device code suffix "4" - see Ordering Information), the module turns ON during a logic High on the On/Off pin and turns OFF during a logic Low. With the Negative Logic On/Off option, (no device code suffix, see Ordering Information), the module turns OFF during logic High and ON during logic Low. The On/Off signal is always referenced to ground. For either On/Off logic option, leaving the On/Off pin disconnected will turn the module ON when input voltage is present. 20 10 0 0.5 1.5 2.5 3.5 Output Voltage (Volts) 4.5 5.5 Figure 41. Output ripple voltage for various output voltages with external 1x10 F, 1x47 F, 2x47 F or 4x47 F ceramic capacitors at the output (20A load). Input voltage is 12V. For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 42. When the external transistor Q1 is in the OFF state, the internal PWM Enable signal is pulled high through an internal 24.9k resistor and the external pullup resistor and the module is ON. When transistor Q1 is turned ON, the On/Off pin is pulled low and the module is OFF. A suggested value for Rpullup is 20k. VIN+ MODULE Safety Considerations Rpullup For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12 (EN60950-1) Licensed. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a fast-acting fuse with a maximum rating of 20 A in the positive input lead.

At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. Rtrim is the external resistor in k Vo is the desired output voltage. Table 1 provides Rtrim values required for some common output voltages. Over Temperature Protection Table 1 To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the overtemperature threshold of 135oC is exceeded at the thermal reference point Tref . The thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart.

The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Output Voltage Programming The output voltage of the 12V TLynxTM module can be programmed to any voltage from 0.69dc to 5.5Vdc by connecting a resistor between the Trim and GND pins of the module. Certain restrictions apply on the output voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input Voltage Set Point Area plot in Fig. 44. The Upper Limit curve shows that for output voltages of 0.9V and lower, the input voltage must be lower than the maximum of 14V. The Lower Limit curve shows that for output voltages of 3.3V and higher, the input voltage needs to be larger than the minimum of 4.5V. 16 Rtrim (K) 690 22.26 13.53 8.519 6.216 3.812 2.644 1.601 By using a 0.5% tolerance trim resistor with a TC of 100ppm, a set point tolerance of 1.5% can be achieved as specified in the electrical specification. Remote Sense The 12V TLynxTM power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage between the S+ and S- pins. The voltage between the S- and GND pins of the module must not drop below -0.2V. If Remote Sense is being used, the voltage between S+ and S- cannot be more than 0.5V larger than the voltage between VOUT and GND. Note that the output voltage of the module cannot exceed the specified maximum value. When the Remote Sense feature is not being used, connect the S+ pin to the VOUT pin and the S- pin to the GND pin.

Circuit configuration for programming output voltage using an external resistor. Voltage Margining Output voltage margining can be implemented in the 12V TLynxTM modules by connecting a resistor, Rmargin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to output pin for margining-down.

Circuit Configuration for margining Output voltage GND Monotonic Start-up and Shutdown The 12V TLynxTM modules have monotonic start-up and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. Startup into Pre-biased Output The 12V Pico TLynxTM 20A modules can start into a prebiased output as long as the prebias voltage is 0.5V less than the set output voltage. Note that prebias operation is not supported when output voltage sequencing is used. Output Voltage Sequencing The 12V TLynxTM modules include a sequencing feature, EZSEQUENCE that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, either tie the SEQ pin to VIN or leave it unconnected. When an analog voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches the set-point voltage. The final value of the SEQ voltage must be set higher than the set-point voltage of the module. The output voltage follows the voltage on the SEQ pin on a one-to-one volt basis. By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. For proper voltage sequencing, first, input voltage is applied to the module. The On/Off pin of the module is left unconnected (or tied to GND for negative logic modules or tied to VIN for positive logic modules) so that the module is ON by default. After applying input voltage to the module, a minimum 10msec delay is required before applying voltage on the SEQ pin. During this time, a voltage of 50mV ( 20 mV) is maintained on the SEQ pin. This delay gives the module enough time to complete its internal power-up soft-start cycle. During the delay time, the SEQ pin should be held close to ground (nominally 50mV 20 mV). This is required to keep the internal op-amp out of saturation thus preventing output December 5, 2019 Figure 47. Circuit showing connection of the sequencing signal to the SEQ pin. After the 10msec delay, an analog voltage is applied to the SEQ pin and the output voltage of the module will track this voltage on a one-to-one volt bases until the output reaches the set-point voltage. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their set-point voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential. When using the EZ-SEQUENCETM feature to control start-up of the module, pre-bias immunity during start-up is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during start-up. When using the EZ-SEQUENCETM feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when the voltage at the SEQ pin is applied. This will result in the module sinking current if a pre-bias voltage is present at the output of the module. When prebias immunity during start-up is required, the EZSEQUENCETM feature must be disabled. For additional guidelines on using the EZ-SEQUENCETM feature please refer to Application Note AN04-008 "Application Guidelines for Non-Isolated Converters: Guidelines for Sequencing of Multiple Modules", or contact the Lineage Power Technical representative for additional information. Power Good The 12V TLynxTM modules provide a Power Good (PGOOD) signal that is implemented with an open-drain output to indicate that the output voltage is within the regulation limits of the power module. The PGOOD signal will be de-asserted to a low state if any condition such as overtemperature, overcurrent or loss of regulation occurs that would result in the output voltage going 11% outside the setpoint value.

Synchronization The 12V TLynxTM series of modules can be synchronized using an external signal. Details of the SYNC signal are provided in the Electrical Specifications table. If the synchronization function is not being used, leave the SYNC pin floating. to select the right value of external R-C to tune the module for best transient performance and stable operation for other output capacitance values or input voltages other than 12V. Table 2. General recommended values of of RTUNE and CTUNE for Vin=12V and various external ceramic capacitor combinations. Tunable LoopTM TLynxTM The 12V 20A modules have a new feature that optimizes transient response of the module called Tunable LoopTM. External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Figure 41) and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes. Adding external capacitance however affects the voltage control loop of the module, typically causing the loop to slow down with sluggish response. Larger values of external capacitance could also cause the module to become unstable. The Tunable LoopTM allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. The Tunable LoopTM is implemented by connecting a series R-C between the SENSE and TRIM pins of the module, as shown in Fig. 47. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module.

Table 2 shows the recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 940 F that might be needed for an application to meet output ripple and noise requirements. Selecting RTUNE and CTUNE according to Table 2 will ensure stable operation of the module. In applications with tight output voltage limits in the presence of dynamic current loading, additional output capacitance will be required. Table 3 lists recommended values of RTUNE and CTUNE in order to meet 2% output voltage deviation limits for some common output voltages in the presence of a 10A to 20A step change (50% of full load), with an input voltage of 12V.
