OPTIONS
Digital PMBus interface
The Delphi Series Q54SG, 42~60V input, isolated single output,
Trim
Quarter Brick, are full digital control DC/DC converters, and are the
Positive On/Off logic
latest offering from a world leader in power systems technology and
Short pin lengths available
manufacturing Delta Electronics, Inc. The Q54SG series provide
up to 600 watts of power in an industry standard, DOSA compliant
footprint and pin out; The typical efficiency is 96.3% at 12V/33A
load. There is a built-in digital PWM controller in the Q54SG series,
which is used to complete the Vo feedback, PWM signal
generation, droop current sharing, fault protection, and PMBUS
communications, and so on. With the digital control, many design
