Description
Delphi NC20 Series Non-Isolated Point of Load DC/DC Power Modules: 12Vin, 0.9V-5.0Vout, 20A
Manufacturer
DELTA [Delta Electronics, Inc.]
Datasheet
Delphi NC20 Series Non-Isolated Point of Load
DC/DC Power Modules: 12Vin, 0.9V-5.0Vout, 20A
The Delphi NC20 Series, 12V 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 NC20 series operates from a 12V nominal input, provides up to
20A of power in a vertical or horizontal mounted through-hole package
and the output can be resistor- or voltage-trimmed from 0.9Vdc to
5.0Vdc. It provides a very cost effective point of load solution. With
creative design technology and optimization of component placement,
these
performance, as well as extremely high reliability under highly stressful
operating conditions.
