Description
Product Brief
The
PHD32
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.
