Delphi NC30 Series Non-Isolated Point of Load
DC/DC Power Modules: 12Vin, 0.9V-5Vout, 30A
The Delphi NC30 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 series operates from a 12V nominal input, provides up
to 30A 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 series has built-in current sharing control and
multiple NC30/NC40 series modules could be paralleled together to
provide even higher output currents. NC30 series 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.
