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 leade

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 outpu

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.
