TYPICAL APPLICATIONS

DESCRIPTION

Amplitude Converter™ (SAC™) operating from a 38 to 55 Vdc

primary bus to deliver an isolated, unregulated 4.8 to 6.9

output. The Sine Amplitude Converter offers a low AC

impedance beyond the bandwidth of most downstream

regulators; therefore capacitance normally at the load can be

located at the input to the Sine Amplitude Converter. Since the

transformation ratio of the B048x060y24A is 1/8, the

capacitance value can be reduced by a factor of 64x, resulting

in savings of board area, materials and total system cost.

The B048x060y24A is provided in a VI Chip package

compatible with standard pick-and-place and surface mount

assembly processes. The co-molded VI Chip package provides

enhanced thermal management due to a large thermal

interface area and superior thermal conductivity. The high

conversion efficiency of the B048x060y24A increases overall

system efficiency and lowers operating costs compared to

conventional approaches.
