Delphi DCL, Non-Isolated Point of Load
DC/DC Power Modules: 4.5~14Vin,
0.69V-5V/20Aout
The Delphi Series DCL, 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 DCL series provides
a programmable output voltage from 0.69 V to 5 V 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 20A 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.
