Q48SG Datasheet, PDF (1/26 Pages) Delta Electronics, Inc. – Industry standard, DOSA compliant pin out

Delphi Series Q48SG Quarter Brick Family
Full Digital Control DC/DC Power Modules:
48V In, 11.8V/42A Out
The Delphi Series Q48SG, 38~75V input, isolated single output,
Quarter Brick, are full digital control DC/DC converters, and are the
latest offering from a world leader in power systems technology and
manufacturing ― Delta Electronics, Inc. The Q48SG series provide
up to 500 watts of power in an industry standard, DOSA compliant
footprint and pin out; the typical efficiency is 95.3% at 48V input,
11.8V output and 42A load. There is a built-in digital PWM controller
in the Q48SG series, which is used to complete the Vo feedback,
PWM signal generation, droop current sharing, fault protection, and
PWBUS communications, and so on. With the digital control, many
design and application flexibility, advanced performance, and
reliability are obtained; and the Q48SG series can be connected in
parallel directly for higher power without add external oring-fet.
