Delphi DCS, Non-Isolated Point of Load
DC/DC Power Modules: 4.5~14Vin, 0.59-5.0V/6Aout
The Delphi Series DCS, 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 DCS series provides a programmable output
voltage from 0.59 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 6A of output
current in an industry standard footprint. With creative design
