Bandwidth: 20MHz, (2us/div) E-mail: dcdc@deltaww.com http://www.deltaww.com/dcdc P7 DESIGN CONSIDERATIONS Input Source Impedance The impedance of the input source connecting to the DC/DC power modules will interact with the modules and affect the stability. A low ac-impedance input source is recommended. A low ESR electrolytic capacitor higher than 100F (ESR < 0.7 at 100kHz) is suggested. Safety Considerations The power module must be installed in compliance with the spacing and separation requirements of the end-user's safety agency standard, i.e. IEC 62368-1: 2014 (2nd edition), EN 62368-1: 2014 (2nd edition), UL 62368-1, 2nd Edition, 2014-12-01 and CSA C22.2 No. 62368-1-14, 2nd Edition, 2014-12, if the system in which the power module is to be used must meet safety agency requirements. Both the input and output of this product meet SELV requirement. This power module is not internally fused. To achieve optimum safety and system protection, an input line fuse is highly recommended. The safety agencies require a normal-blow fuse with 70A maximum rating to be installed in the ungrounded lead. A lower rated fuse can be used based on the maximum inrush transient energy and maximum input current. Soldering and Cleaning Considerations Synchronization The module will synchronize its switching to a clock signal at the Sync pin (relative to Sense-) of between 250KHz and 350KHz. For noise immunity, the input has 0.1V hysteresis. It can be driven by any standard logic gate. The input has an internal 5K pull-up to 3.3V; if unused, leave this input floating or tie it directly to Sense-. Output Voltage Set Point The output voltage can be programmed to any voltage between 0 V dc and Vmax by connecting one resistor between the Vset(Trim) pin (9) and Sense- (8); See Figure 15. For a desired output voltage, the value of the resistor should be: 11830 V max 10912 Rvset (vset ) Vset 0.058 V max Alternatively, the Vset(Trim) pin can be driven from an external voltage source: Vset Vvset (Vset ) 2.366 2.316 V max Vset = desired output voltage set point Vmax = maximum rated output voltage (60V) Undriven, this pin floats at 2.5V which sets the output to 0V. Post solder cleaning is usually the final board assembly process before the board or system undergoes electrical testing. Inadequate cleaning and/or drying may lower the reliability of a power module and severely affect the finished circuit board assembly test. Adequate cleaning and/or drying is especially important for un-encapsulated and/or open frame type power modules. For assistance on appropriate soldering and cleaning procedures, please contact Delta's technical support team. Remote On/Off The remote on/off feature on the module is negative logic. Negative logic turns the module on during logic low and off during logic high. Remote on/off can be controlled by an external switch between the on/off terminal and the VIN (-) terminal. The switch can be an open collector or open drain. For negative logic if the remote on/off feature is not used, please short the on/off pin to VIN (-). Figure 15 Output Current Setting The maximum output current (effectively the current limit) can be reduced to any value between 0 and Imax by connecting one resistor between the Iset pin (4) and Sense- (8); see Figure 15. The value of the resistor should be: RIset (Iset ) 25Iset 3.3 Im ax 2.5Iset Alternatively, the Iset pin can be driven from an external voltage source: Iset Viset (Iset ) 2.5 Imax Iset = desired output current set point Imax = maximum rated output current (50A) Undriven, Iset pin floats to 3.3V which sets the current limit at its nominal value of 110% * Imax. Figure 14: Remote On/Off Implementation Datasheet DS_H60SB0A050_05162018 E-mail: dcdc@deltaww.com http://www.deltaww.com/dcdc P8 FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will shut down and enter latch mode. Need to repower input voltage to turn on the module. Over-Voltage Protection The modules include an internal input over-voltage protection circuit and output voltage protection circuit, which monitors the voltage on the input terminals and the output terminals. If this voltage exceeds the over-voltage set point, the protection circuit will shut down, and then restart with a time delay after the fault no long exist. Over-Temperature Protection The over-temperature protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the over-temperature threshold the module will shut down. The module will restart after the temperature is within specification. Parallel The modules provide active current sharing mode. For the active current sharing: it permits maximum 8% output voltage deviation between two modules By connecting the Vout pin and Ishare pin of the parallel module together, the current sharing can be realized automatically. The module can be parallel directly for higher power without adding external oring-fet. And the failure of a power supply should not affect the load sharing or output voltages of the other supplies still operation For a normal parallel operation the following precautions must be observed: 1. The current sharing accuracy equation is: X% = | Io1-Io2 | / Irate, Where, Io1 is the output current of module1; Io2 is the output current of module2 Irate is the rated full load current of per module. 2. To ensure a better steady current sharing accuracy, below design guideline should be followed: a) The inputs of the converters must be connected to the same voltage source; and the PCB trace resistance from Input voltage source to Vin+ and Vin- of each converter should be equalized as much as possible. b) The PCB trace resistance from each converter's output to the load should be equalized as much as possible. c) For accurate current sharing accuracy test, the module should be soldered in order to avoid the unbalance of the touch resistance between the modules to the test board. 3. To ensure the parallel module can start up monotonically without trigging the OCP circuit, below design guideline should be followed: a) Before all the parallel modules finished start up, the total load current should be lower than the rated current of 1 module. b) The ON/OFF pin of the converters should be connected together to keep the parallel modules start up at the same time. c) The under voltage lockout point will slightly vary from unit to unit. The dv/dt of the rising edge of the input source voltage must be greater than 1V/ms to ensure that the parallel module start up at the same time. PMBus Communication Figure 16: Parallel and current sharing configuration The module has a digital PMBus interface to allow the module to be monitored, controlled and configured by the system. The module supports 3 PMBus signal lines, Data, Clock, SMBALERT (optional), and 2 Address line Addr0 and Addr1. More detail PMBus information can be found in the PMB Power Management Protocol Specification, Part I and part II, revision 1.2; which is shown in http://pmbus.org . Both 100kHz and 400kHz bus speeds are supported by the module. Connection for the PMBus interface should be following the High Power DC specifications given in section 3.1.3 in the SMBus specification V2.0 or the Low Power DC specifications in section 3.1.2. The complete SMBus specification is shown in http://smbus.org. The module supports the Packet Error Checking (PEC) protocol. It can check the PEC byte provided by the PMBus master, and include a PEC byte in all message responses to the master. Datasheet DS_H60SB0A050_05162018 E-mail: dcdc@deltaww.com http://www.deltaww.com/dcdc P9 FEATURES DESCRIPTIONS SMBALERT protocol is also supported by the module. SMBALERT line is also a wired-AND signal; by which the module can alert the PMBUS master via pulling the SMBALERT pin to an active low. There are two ways that the master and the module response to the alert of SMBALERT line. One way is for the module used in a system that does not support Alert Response Address (ARA). The module is to retain it's resistor programmed address, when it is in an ALERT active condition. The master will communicate with the slave module using the programmed address, and using the various READ_STATUS commands to find who cause for the SMBALERT. The CLEAR_FAULTS command will clear the SMBALERT. The module contains a data flash used to store configuration settings, which will not be programmed into the device data flash automatically. The STORE_DEFAULT_ALL command must be used to commit the current settings are transfer from RAM to data flash as device defaults PMBUS Addressing The Module has flexible PMBUS addressing capability. When connect different resistor from Addr0 and Addr1 pin to GND pin, 64 possible addresses can be acquired. The address is in the form of octal digits; Each pin offer one octal digit, and then combine together to form the decimal address as shown in below. Address = 8 * ADDR1 + ADDR0 Corresponded to each octal digit, the requested resistor values are shown in below, and +/-1% resistors accuracy can be accepted. If there is any resistances exceeding the requested range, address 127 will be return. 0-12 and 40, 44, 45, and 55 in decimal address can't be used, since they are reserved according to the SMBus specifications, and which will also return address 127. Octal digit 0 1 2 3 4 5 6 7 Datasheet DS_H60SB0A050_05162018 PMBus Data Format The module receives and report date in LINEAR format. altering the exponent is supported. DIRECT format is not supported by the module. For commands that set or report any voltage thresholds related to the output voltage, the module supports the linear data format consisting of a two byte value with a 16-bit, unsigned mantissa, and a fixed exponent of -9. The format of the two data bytes is shown below: The equation can be written as: Vout = Mantissa x 2-9 For example, considering set Vout to 12V by VOUT_COMMAND, the read/write data can be calculated refer to below process: 1. Mantissa =Vout/2-9= 12/2-9=6144; 2. Converter the calculated Mantissa to hexadecimal 0x1800. For commands that set including input voltages, output current, temperature, time and frequency, the format of the two data bytes is shown as in below: For example, considering set the turn on threshold of input under voltage lockout to 34V by VIN_ON command; the read/write data can be calculated refer to below process: 1. The read Vin value is hexadecimal E910 2. The high 5 bit in binary is 11101, so the Mantissa is 2-3. 3. Low 11 bits 00100010000, in decimal is 272 4. So the real Vin value is 272/2-3 is 34v.

To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected.

Delta recommended soldering methods and process parameters are provided in this document for solder attachment of power modules onto system board. SAC305 is the suggested lead-free solder alloy for all soldering methods. Reflow soldering is not a suggested method for through-hole power modules due to many process and reliability concerns. If you have this kind of application requirement, please contact Delta sales or FAE for further confirmation. Wave Soldering (Lead-free) Delta's power modules are designed to be compatible with single-wave or dual wave soldering. The suggested soldering process must keep the power module's internal temperature below the critical temperature of 217 continuously. The recommended wave-soldering profile is shown in following figure. Recommended Temperature Profile for Lead-free Wave Soldering Note: The temperature is measured on solder joint of pins of power module. The typical recommended (for double-side circuit board) preheat temperature is 115+/-10 on the top side (component side) of the circuit board. The circuit-board bottom-side preheat temperature is typically recommended to be greater than 135 and preferably within 100 of the solder-wave temperature. A maximum recommended preheat up rate is 3 /s. A maximum recommended solder pot temperature is 255+/-5 with solder-wave dwell time of 3~6 seconds. The cooling down rate is typically recommended to be 6/s maximum. Datasheet DS_H60SB0A050_05162018 E-mail: dcdc@deltaww.com http://www.deltaww.com/dcdc P21 Hand Soldering (Lead Free) Hand soldering is the least preferred method because the amount of solder applied, the time the soldering iron is held on the joint, the temperature of the iron, and the temperature of the solder joint are variable. The recommended hand soldering guideline is listed in Table 1. The suggested soldering process must keep the power module's internal temperature below the critical temperature of 217 continuously.
