The VTM current multiplier is a DC-DC converter with a very fast transient response, an isolation voltage of 2,250VDC, and a fixed voltage conversion ratio that can be placed in PoL.
The VI Chip® Current multiplier is a high efficiency Sine Amplitude Converter™ (SAC) that operates on a 26-55 or 0-60VDC primary bus and provides an isolated output. Sine wave amplitude converters provide low AC impedance that exceeds the bandwidth of most downstream regulators.

Therefore, typically the capacitance at the load can be located at the input to the sine wave amplitude converter. For example, if the K-factor is 1/4, the capacitance value can be reduced by a factor of 16, resulting in savings in board area, materials, and overall system cost.

It comes in a VI chip package that is compatible with standard pick-and-place and surface-mount assembly processes. The integrally molded VI chip package provides enhanced thermal management with a large thermal interface area and excellent thermal conductivity. High conversion efficiency increases overall system efficiency and reduces operating costs compared to traditional approaches.
It provides efficiency and size benefits by enabling the use of Factorized Power Architecture™, reducing conversion and distribution losses, and facilitating dense point-of-load conversion.
It can also be combined with a PRM regulator to configure a high efficiency, high power density isolated DC-DC converter.
