(sac?) operating from a 0 to 55 vdc primary bus to deliver a 0 to 2.3 vdc low voltage output. 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 VTM48KP020X088AA1 is 1/24, the capacitance value can be reduced by a factor of 576, resulting in savings of board area, materials and total system cost. the VTM48KP020X088AA1 is provided in vicors 1323 chip package compatible with standard pick-and-place assembly processes. the co-molded chip package provides enhanced thermal management due to a large thermal interface area and superior thermal conductivity. the high conversion efficiency of the VTM48KP020X088AA1 increases overall system efficiency and lowers operating costs compared to conventional approaches. the VTM48KP020X088AA1 enables the utilization of factorized power architecture? which provides efficiency and size bene?ts by lowering conversion and distribution losses and promoting high density point of load conversion. product ratings v in = 0 to 55 v i out = 88 a (nom) v out = 0 to 2.3 v (no load) k = 1/24
