Delphi Series DNQ12, Non-Isolated, Point of Load

DC/DC Power Modules: 10-14Vin, 0.8V-5.5V/25A out

The Delphi series DNQ12S, 10V~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 DNQ12S series provides a programmable output voltage from 0.8V to

5.5V using an external resistor. This product family is available in a surface

mount or SIP package and provides up to 25A of current. With creative

design technology and optimization of component placement, these

converters possess outstanding electrical and thermal performance and

extremely high reliability under highly stressful operating conditions.
