Product Brief PHD32 Series – 32A Non-Isolated DC/DC Converter 5V, 3.3V Input Dual Output Features • • • • • • • • Two independently regulated outputs Efficiency in excess of 90% 32A of combined output current at 65°C and 200LFM Flexible output load distribution Output overcurrent protection Remote ON/OFF Output voltage trim adjust for each output Through hole and SMT configurations Description The PHD32 series converters are non-isolated dual output DC/DC converters available in through hole and surface mount configurations. The products provide point of load conversion of a single 3.3V or 5V input voltage to two independently regulated low output voltages. Each output can provide up to 20A of output current, has independent feedback loop and independent trim function. Two power trains operate out of phase thus significantly reducing ripple current requirements and simplifying external filtering. High efficiency, low space requirements, and flexible loading characteristics make the converters an ideal choice for powering of high performance multivoltage ASICs. 3.3V input Model PHD32UDD PHD32UDC PHD32UDB PHD32UDA PHD32UDY PHD32UCC PHD32UCB PHD32UCA PHD32UCY PHD32UBB PHD32UBA PHD32UBY PHD32UAA PHD32UAY PHD32UYY 3.3V Input Input Vout1, voltage VDC range, VDC 3.0-3.6 2.5 3.0-3.6 2.5 3.0-3.6 2.5 3.0-3.6 2.5 3.0-3.6 2.5 3.0-3.6 2.0 3.0-3.6 2.0 3.0-3.6 2.0 3.0-3.6 2.0 3.0-3.6 1.8 3.0-3.6 1.8 3.0-3.6 1.8 3.0-3.6 1.5 3.0-3.6 1.5 3.0-3.6 1.2 Vout2, VDC Eff. % 5V input Model 2.5 2.0 1.8 1.5 1.2 2.0 1.8 1.5 1.2 1.8 1.5 1.2 1.5 1.2 1.2 91 90 89 89 88 89 88 88 87 88 87 86 86 85 84 PHD32VEE PHD32VED PHD32VEC PHD32VEB PHD32VEA PHD32VEY PHD32VDD PHD32VDC PHD32VDB PHD32VDA PHD32VDY PHD32VCC PHD32VCB PHD32VCA PHD32VCY PHD32VBB PHD32VBA PHD32VBY PHD32VAA PHD32VAY PHD32VYY Both outputs of the PHD32U and PHD32V can be loaded up to twenty (20) amps each.
