Description
The VI Chip^® current multiplier is a high efficiency (>95%)
Sine Amplitude Converter™ (SAC) operating from a
26 to 55V_DC 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
VTM48EF096T025A00 is 1/5, the capacitance value can be
reduced by a factor of 25, resulting in savings of board area,
materials and total system cost.
The VTM48EF096T025A00 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 VTM48EF096T025A00 increases overall system
efficiency and lowers operating costs compared to conventional
approaches.
The VTM48EF096T025A00 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.
