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.
