APPLICATIONS 

Delphi NC15 Series Non-Isolated Point of Load 
DC/DC Power Modules: 12Vin, 0.9V-5.0Vout, 15A

 

The Delphi NC15 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 NC15 series operates from a 12V nominal input, provides up to 15A 
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.
