Half brick converters offer ultra wide input range

XP Power has released the QSB150 series of 150W half brick DC-DC converters. It is aimed at a wide range of applications where an ultra-wide input range is required. The devices adhere to the industry standard half brick footprint of 61.5mm x 57.9mm x 12.7mm and having pin out compatibility with existing industry standards, the device is highly efficient, typically up to 92%. The range is available in six regulated single output models, covering all the popular nominal output voltages from +12VDC to +48VDC, a voltage trim function allows adjustment of +/-10% of stated output if required to accommodate line losses or non-standard voltage requirements. With an ultra-wide input range of 9VDC-75VDC these units accept all nominal inputs of 12VDC, 24VDC and 48VDC. By accepting three nominal battery voltages, the QSB150 negates the need for a change in end equipment. Input to output isolation is 1,500VDC. A remote on/off input provides a method of sequencing start up and providing external control of the unit. This series of converters can operate in a wide range of environments and temperatures from -40C to a maximum base plate temperature of +100C.
