TYPICAL APPLICATIONS

DESCRIPTION

Amplitude Converter™ (SAC™) operating from a 360 to 400

Vdc primary bus to deliver an isolated 45 – 50 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 regulator can be located at the input to the SAC. Since the

K factor of the BCM384F480T325A00 is 1/8, that capacitance

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

board area, materials and total system cost.

compatible with standard pick-and-place and surface mount

thermal management through its low junction-to-case and

junction-to-board thermal resistance. With high conversion

efficiency the BCM384F480T325A00 increases overall system

efficiency and lowers operating costs compared to

conventional approaches.
