Delphi Series Q48SB, 300W Bus Converter
DC/DC Power Modules: 48V in, 9.6V/31A 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 up
to 31A 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 4:1 unregulated output of
12V at 20A or 25A. The Q48SB108 features a wider input voltage range of
36V to 60V and provides 5:1 unregulated output of 9.6V at up to 31A.
Typical efficiency for the 9.6V/31A or 10.8V/28A module is 95.5%. 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.
