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

The Delphi Series DNM04, 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 a surface

mount or SIP package and provides up to 10A 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.
