The VTM48EH015T050A00 is a V•I Chip™ current multiplier it has high efficiency (>89%) Sine Amplitude Converter™ (SAC™) operating from a 26 to 55 Vdc primary bus to deliver an isolated output. The Sine Amplitude Converter offers a low AC impedance beyond the bandwidth of most downstream regulators, which means that capacitance normally at the load can be located at the input to the Sine Amplitude Converter. Since the K factor of the VTM48EH015T050A00 is 1/32, that capacitance value can be reduced by a factor of 1024, resulting in savings of board area, materials and total system cost.

The VTM48EH015T050A00 is provided in a V•I Chip package compatible with standard pick-and-place and surface mount assembly processes. The co-molded V•I Chip package provides enhanced thermal management due to large thermal interface area and superior thermal conductivity. With high conversion efficiency the VTM48EH015T050A00 increases overall system efficiency and lowers operating costs compared to conventional approaches.
