VICOR BCM48BT240M300A00

The bus converter is a high efficiency (>94%) Sine Amplitude Converter (SAC) operating from a 38 to 55V DC primary bus to deliver an isolated, ratiometric output voltage from 19.0 to 27.5V DC. 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 converter is 1/2, the capacitance value can be reduced by a factor of 4×, resulting in savings of board area, materials and total system cost. The converter 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 converter increases overall system efficiency and lowers operating costs compared to conventional approaches.
