Delphi Series Q48DM, 75W Quarter Brick,
Dual Output DC/DC Power Modules:
3.3V/12A and 1.2V/25A
The Delphi Series Q48DM Quarter Brick, 48V input, dual output,
isolated DC/DC converters are the latest offering from a world leader
in power system and technology and manufacturing — Delta
Electronics, Inc. This product family provides up to 75 watts of dual
positive regulated outputs with a flexible combination of output current
and in a very cost effective industry standard footprint. Both output
channels can be used independently. There is a trim function to be
used with the second output voltage (the lower output voltage). 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. All models are fully protected from abnormal
input/output voltage, current, and temperature conditions. The Delphi
Series Q48DM converters meet all safety requirements with basic
insulation.
