Delphi Series Q48SB, 300W Bus Converter DC/DC Power Modules: 48V in, 12V/25A out

The Delphi Series Q48SB, 48V input, single output, quarter brick, 300W bus converters are the latest offering from a world leader in power systems technology and manufacturing -- Delta Electronics, Inc. This product family supports intermediate bus architectures and powers multiple downstream non-isolated point-of-load (POL) converters. The Delphi Series Q48SB operates from a nominal 48V input and provides up to 300W of power or 28A of output current in an industry standard quarter brick footprint. The Q48SB product currently supports two input ranges: the Q48SB120 features an input voltage range of 42V to 53V and provides an unregulated output of 12V at 20A or 25A. The Q48SB108 features a wider input voltage range of 36V to 60V and provides an unregulated output of 10.8V at up to 28A. Typical efficiency for the 12V/25A module is 96%. With optimized component placement, creative design topology, and numerous patented technologies, the Q48SB bus converter delivers outstanding electrical and thermal performance. An optional heatsink is available for harsh thermal requirements.
