DESCRIPTION
The VI Chip® current multiplier is a high efficiency (>94%) 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; 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
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 VTM48EF015T115A00 increases
overall system efficiency and lowers operating costs compared
to conventional approaches.
The VTM48EF015T115A00 enables the utilization of Factorized
Power Architecture™ which provides efficiency and size
benefits by lowering conversion and distribution losses and
promoting high density point of load conversion.
