Q48SD Datasheet, PDF (1/24 Pages) Delta Electronics, Inc. – Industry standard, DOSA compliant pin out

Delphi Series Q48SD Quarter Brick Family
Full Digital Control DC/DC Power Modules:
48V in, 12V/25A out
The Delphi Series Q48SD, 36~75V 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 Q48SD series provide
up to 400 watts of power in an industry standard, DOSA compliant
footprint and pin out; the typical efficiency is 96% at 48V input, 12V
output and 33A load. There is a built-in digital PWM controller in the
Q48SD series, which is used to complete the Vo feedback, PWM
signal generation, active 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 Q48SD series can be connected in
parallel directly for higher power without add external oring-fet.
