Delphi DNM24 series Non-Isolated Point of Load
DC/DC Power Modules: 20-30Vin, 5-15V/10A out
OPTIONS
The Delphi series DNM24S, 20~30V 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 DNM24S series provides a programmable output voltage from
5V to 15V through an external trimming resistor. This product family is
available in SIP package and provides 10A of output current in an
industry standard footprint and pinout. 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.
