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 APPLICATIONS optimization of component placement, these converters possess DataCom outstanding electrical and thermal performance, as well as extremely Distributed power architectures high reliability under highly stressful operating conditions.
