Description
The Cool-Power® PI3101 is a very high density isolated DC-DC converter implementing a high efficiency soft-switching power architecture. The PI3101 operates over a wide range input of 36 V to 75 Vdc, delivering ~60 W of output power (3.3 Vout @ 18 A), yielding an unprecedented power density of 400 W/in3, achieving 3-4 times the power density of alternate solutions. The PI3101 is available in a space saving surface mountable 0.87″ x 0.65″ x 0.27″ package, achieving ~50% space reduction versus conventional solutions.
