Delphi DNM, Non-Isolated Point of Load 

DC/DC Power Modules: 2.8-5.5Vin, 0.75-3.3V/10Aout

 

The Delphi Series DNM, 2.8-5.5V input, single output, non-isolated 
Point of Load DC/DC converters are the latest offering from a world 
leader in power system and technology and manufacturing 

 Delta 

Electronics, Inc. The DNM04 series provides a programmable output 
voltage from 0.75V to 3.3V using an external resistor. The DNM series 
has 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 surface 
mount or SIP packages and provides up to 10A 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.
