Details, datasheet, quote on part number: QSB15048WS28

XP Power announces the QSB150 series of 150 W half brick DC-DC converters aimed at a wide range of applications where an ultra-wide input range are required. Conforming to the industry standard half brick footprint of 61.5 mm x 57.9 mm x 12.7 mm (2.40 inches x 2.28 inches x 0.50 inches) and having pin out compatibility with existing industry standards, the QSB150 is highly efficient, typically up to 92%. Available in six regulated single output models covering all the popular nominal output voltages from 12 VDC to 48 VDC, a voltage trim function allows adjustment of ±10% of stated output if required to accommodate line losses or non-standard voltage requirements.
