Delphi NC20 Series Non-Isolated Point of Loadwww.DataSheet4U.com
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 converters possess outstanding electrical and thermal
performance, as well as extremely high reliability under highly stressful
operating conditions.
