Delphi NC Series Non-Isolated Point of Load

DC/DC Power Modules: 12Vin, 0.9V-5Vout, 30A/40A

The Delphi NC30/NC40 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 NC30/NC40 series operates from a 12V nominal
input, provides up to 40A 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. NC30/NC40 series has built-in
current sharing control and multiple NC30/NC40 series modules could
be paralleled together to provide even higher output currents.
NC30/NC40 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.
