Product Description
The VI Chip® current multiplier is a high efficiency
Sine Amplitude Converter™ (SAC™) operating from a
26 to 50 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. This allows for a
reduction in point of load capacitance of typically >100x which
results in a saving of board area, materials and
total system cost.
The VTM current multiplier 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 large thermal interface
area and superior thermal conductivity. With high conversion
efficiency the VTM current multiplier increases overall system
efficiency and lowers operating costs compared to
conventional approaches.
The VTM current multiplier enables the utilization of
Factorized Power Architecture providing efficiency and size
benefits by lowering conversion and distribution losses and
promoting high density point of load conversion.

Using the MIL-COTs PRM, the output of the VTM is regulated over the load current range with only a single interconnect
between the PRM and VTM and without the need for isolation in the feedback path.
