DESCRIPTION

The V

Amplitude Converter

primary bus to deliver an isolated 12 V nominal, unregulated

secondary. The SAC offers a low AC impedance beyond the

bandwidth of most downstream regulators, meaning that

input capacitance normally located at the input of a 12 V

regulator can be located at the input to the SAC. Since the

K factor of the BCM48BH120T120A00 is 1/4, that capacitance

value can be reduced by a factor of 16x, resulting in savings of

board area, materials and total system cost.

The BCM48BH120T120A00 is provided in a V

compatible with standard pick-and-place and surface mount

assembly processes. The V

thermal management through its low junction-to-case and

junction-to-board thermal resistance. With high conversion

efficiency the BCM48BH120T120A00 increases overall system

efficiency and lowers operating costs compared to

conventional approaches.
