FEATURES

DESCRIPTION

The VI Chip^®current multiplier is a high efficiency (>91%)

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, which

means that capacitance normally at the load can be located

at the input to the Sine Amplitude Converter. Since the K factor

of the VTM48EH020T040A00 is 1/24, that capacitance value

can be reduced by a factor of 576, resulting in savings of board

area, materials and total system cost.

The VTM48EH020T040A00 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 VTM48EH020T040A00 increases overall system

efficiency and lowers operating costs compared to conventional

approaches.

• 48 Vdc to 2 Vdc 40 A current multiplier

- Operating from standard 48 V or 24 V PRM regulators

• High efficiency (>91%) reduces system power

consumption

• High density (267 A/in³)

• “Half Chip” VI Chip^®package enables surface mount,

low impedance interconnect to system board

• Contains built-in protection features against:

- Overvoltage

- Overcurrent

- Short Circuit

- Overtemperature

• Provides enable/disable control, internal temperature

monitoring, current monitoring

• ZVS/ZCS resonant Sine Amplitude Converter topology

The VTM48EH020T040A00 enables the utilization of Factorized

Power Architecture^TMproviding efficiency and size benefits by

lowering conversion and distribution losses and promoting high

density point of load conversion.

• Less than 50 ºC temperature rise at full load

in typical applications
