Data Sheet: AscetaTM iQL Series –Single Output Quarter Brick
Asceta™ iQL Series DC/DC Power Modules 48V Input, 3.3V / 60A /198W Output Quarter Brick
The Asceta™ power module series provides exceptionally high true useable power in an industry standard quarter brick format. Its 91% full load efficiency (92% at 70% load) and superior thermal performance make the Asceta series of DC-DC converters is ideally suited for tight space, power-hungry, and thermal challenging distributed power architectures in demanding thermal environments. This rugged building block is designed to serve as the core of your high reliability system. A wide output voltage trim range, -20 to +10%, and remote sensing are standard feature enhancing versatility.
