directives
OPTIONS
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.
