TYPICAL APPLICATION

DESCRIPTION

to 48 Vdc primary bus to deliver an isolated 3.3 V secondary.

The Sine Amplitude Converter offers a low AC impedance

beyond the bandwidth of most downstream regulators, which

means that capacitance normally at the load can be located at

the input to the Sine Amplitude Converter. Since the K factor of

the VIV0104THJ is 1/12, that capacitance value can be reduced

by a factor of 144x, resulting in savings of board area, materials

and total system cost.

with standard pick-and-place and surface mount assembly

management through its low junction-to-case and junction-to-

board thermal resistance. With high conversion efficiency the

VIV0104THJ increases overall system efficiency and lowers

operating costs compared to conventional approaches.

The VIV0104THJ enables the utilization of Factorized Power

Architecture – providing efficiency and size benefits by lowering

conversion and distribution losses and promoting high density

point of load conversion.
