Delphi Series Q48SX, 35A Quarter Brick
DC/DC Power Modules: 48V in, 3.3V and 5.0V out
The Delphi Series Q48SX (XENA TM 100), Quarter Brick, 48V input,
single output, isolated DC/DC converters are the latest offering from a
world leader in power systems technology and manufacturing ― Delta
Electronics, Inc. The Q48SX product family provides up to 125 watts of
power or 35A of output current in an industry standard quarter brick
footprint and pinout. The open frame construction is optimized for
convection cooling over a wide operational ambient temperature range.
With creative design technology and optimization of component
placement, these converters possess outstanding electrical and thermal
performance, as well as extremely high reliability under highly stressful
operating conditions. The output trim pin also serves as a
synchronization function that can greatly reduce output ripple/noise
when multiple Q48SX modules are used and linked together. This is a
big boost to those applications that are extremely noise sensitive. All
Q48SX models are fully protected from abnormal input/output voltage,
current, and temperature conditions. The Delphi Series converters meet
all safety requirements with basic insulation.
