Delphi Series Q48SG Quarter Brick Family
Full Digital Control DC/DC Power Modules:
48V In, 11.8V/34A 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 400 watts of power in an industry
standard, DOSA compliant footprint and pin out; the typical
efficiency is 96% at 48V input, 11.8V output and 34A 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.
