Description

The V375B48C300B uses 2nd Generation power processing, control and packaging technologies to provide the performance, flexibility and cost effectiveness expected of a mature power component.

For example, V375B48C300B, a plated-cavity core transformer couples widely separated primary and secondary windings, resulting in low in-to-out parasitic capacitance and noise.

High frequency ZCS/ZVS switching, V375B48C300B, advanced power semiconductor packaging and thermal management provide high power density with low temperature gradients. Extensive use of silicon integration results in 1/3 the part count  of a 1st Generation converter.
