Description
n Double-sided cooling
A Sine Amplitude Converter (SAC®) that offers superior performance,
the highest efficiency, and highest power density in the smallest
package available. NBMs provide an intermediate bus voltage to
power PoL (point-of-load) converters or serve as a voltage source for
telecom/datacom and transportation applications.
