Product Brief PLD08 Series – 8A Non-Isolated DC/DC Converter 5V, 3.3V Input Dual Output Features • • • • • • • • • Surface mount configuration 1.56” by 0.55” low profile package Two independently regulated outputs Efficiency in excess of 90% 8A 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 Description The PLD08 series converters are surface mount non-isolated dual output DC/DC converters. The products provide point of load conversion of a single 3.3V or 5V input voltage into two independently regulated low output voltages. Each output can provide up to 5A 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 multivoltage ASICs. 3.3V input Model PLD08UDD PLD08UDC PLD08UDB PLD08UDA PLD08UDY PLD08UCC PLD08UCB PLD08UCA PLD08UCY PLD08UBB PLD08UBA PLD08UBY PLD08UAA PLD08UAY PLD08UYY 3.3V Input Input Vout1, voltage VDC range, VDC 3.15-3.6 2.5 3.15-3.6 2.5 3.15-3.6 2.5 3.15-3.6 2.5 3.15-3.6 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 92 91 91 90 90 91 90 89 89 89 89 88 88 86 85 PLD08VEE PLD08VED PLD08VEC PLD08VEB PLD08VEA PLD08VEY PLD08VDD PLD08VDC PLD08VDB PLD08VDA PLD08VDY PLD08VCC PLD08VCB PLD08VCA PLD08VCY PLD08VBB PLD08VBA PLD08VBY PLD08VAA PLD08VAY PLD08VYY Both outputs of the PLD08U and PLD08V can be loaded up to five (5) amps each.
