QRW Series

36-75Vin | 25 / 40 Amps | 1/4 Brick
 

The latest advance in dc-dc converters, the QRW series provides up to 40A output current in an industry standard quarter brick, which makes it an ideal choice for small space, high current and low voltage applications. Designed for optimum efficiency and power density, this module achieves an ultra high efficiency rating of 91% at 3.3V full load, eliminating the need for a heat sink in most applications. Thanks to the ultra high efficiency of this converter, the power dissipation is such that for most applications a heat sink is not required. In addition, the QRW series supports future migration of semiconductor and microprocessor supply voltages down to 1.2V.
