Delphi Series Q48SB, 500W Bus Converter
DC/DC Power Modules: 48V in, 9.6V/55A out
The Delphi Series Q48SB, 48V input, single output, quarter brick, 500W
bus converter is 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
Q48SB9R6 (5:1) operates from a nominal 48V input and provides up to
500W of power or up to 63A (@ 38Vin) of output current in an industry
standard quarter brick footprint. The Q48SB 5:1 bus converter operates
with 500W constant output power, hence when input voltage drops, the
output current will increase accordingly. Typical efficiency for the
9.6V/50A output is 96.8%. 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.
