Delphi series DNT12 Non-Isolated Point of Load

DC/DC Power Modules: 8.3~14Vin, 0.75~5.5Vo, 3A/5A

The Delphi series DNT12, 8.3V~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 DNT12

series provides a programmable output voltage from 0.75V to 5.5V using an

external resistor. This product family is available in a surface mount or SIP

package and provides up to 3A or 5A of current in an industry standard

footprint. 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.
