Delphi DNT04, Non-Isolated Point of Load 

DC/DC Power Modules: 2.4~5.5Vin, 0.75~3.63Vo, 3A out

 

The Delphi Series DNT04, 2.4-5.5V 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 DNT04 series provides a programmable output

voltage from 0.75V to 3.63V via external resistors. This product family is

available in surface mount or SIP package and provides up to 3A of

output current in an industry standard footprint. With creative design

technology and optimization of component placement, these converters

possess outstanding electrical and thermal performance, as well as

extremely high reliability under highly stressful operating conditions.

The DNT04, 

3A

 modules have excellent thermal performance and can

provide full output current at up to 85

 ambient temperature with no

airflow.
