DESCRIPTION
The VI Chip current multiplier is a high efficiency (>96%)
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
V048x060y040A is 1/8, the capacitance value can be reduced
by a factor of 64, resulting in savings of board area, materials
and total system cost.
The V048x060y040A 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 V048x060y040A increases overall
system efficiency and lowers operating costs compared to
conventional approaches.
The V048x060y040A 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.
