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.
