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.
