Delphi DCM, Non-Isolated Point of Load
DC/DC Power Modules: 2.4-5.5Vin,
0.6-3.3V/12Aout
The Delphi Series DCM, 2.4-5.5V 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 0.6V to 3.3V 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.
