Description
The QBW025A0B series of DC-DC converters are new generation of DC-DC power modules designed to support 12Vdc
intermediate bus applications where multiple low voltages are subsequently generated using discrete/modular point of
load (POL) converters. The QBW025A0B series provide up to 25A output current in an industry standard quarter brick,
which makes it well suited for high power 12V intermediate bus voltage applications. The converter incorporates
synchronous rectification technology and innovative packaging techniques to achieve efficiency reaching 95% at 12V full
load. This leads to lower power dissipations such that for many applications a heat sink is not required.
The QBW025A0B series power modules are isolated DC-DC converters that operate over an input voltage range from 36
to 75 Vdc and provide a single regulated 12V output. The output is fully isolated from the input, allowing versatile polarity
configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external
filtering.
RoHS Compliant
