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.
