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.
