Delphi Series DNK12, Non-Isolated, Point of Load
DC/DC Power Modules: 6~14Vin, 0.8V~5.5V/30Aout
The Delphi series DNK12, 6V~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 DNK12 series provides a programmable output voltage from 0.8V to
5.5V by using an external resistor. The DNK converters have flexible and
programmable tracking and sequencing features to enable a variety of
startup voltages as well as sequencing and tracking between power
modules. This product family is available in a surface mount or SIP
package and provides up to 30A of current in an industry standard
footprint. With creative design technology and optimization of component
