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 K factor of the VTM48EF015T115A00 is 1/32, the capacitance value can be reduced by a factor of 1024, resulting in savings of board area, materials and total system cost. The VTM48EF015T115A00 is provided in a VI Chip® package patible 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 VTM48EF015T115A00 increases overall system efficiency and lowers operating costs pared to conventional approaches. The VTM48EF015T115A00 enables the utilization of Factorized Power Architecture™ which provides efficiency and size benefits by lowering conversion and...
