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.
