Delphi DCM, Non-Isolated Point of Load
DC/DC Power Modules: 4.5~14Vin,
0.69-5.0V/12Aout
The Delphi Series DCM, 4.5-14V input, single output,
non-isolated Point of Load DC/DC converters are the latest
offering from a world leader in power systems technology
and manufacturing -- Delta Electronics, Inc. The DCM
series provides a programmable output voltage from 0.69
V to 5.0V using an external resistor and has flexible and
programmable tracking features to enable a variety of
startup voltages as well as tracking between power
modules. This product family is available in surface mount
and provides up to 12A of output current in an industry
standard footprint. 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
