PRM48BT480T500A00

The VI Chip® PRMTM Regulator is high efficiency converter, operating from a 38.0 to 55.0 Vdc input to generate a regulated 20.0 to 55.0 Vdc output. The ZVS buck-boost topology enables high switching frequency operation with high conversion efficiency. High switching frequency reduces the size of reactive components enabling power density up to 1676 W/in3.

The Half VI Chip® package is compatible with standard pick and-place and surface mount assembly processes with a planar thermal interface area and superior thermal conductivity.

In a Factorized Power Architecture system, the PRM and downstream VTMTM current multiplier minimize distribution and conversion losses in a high power solution, providing an isolated, regulated output voltage.

In Remote Sense Operation, the internal regulation circuitry is disabled, and an external control loop and current sensor maintain regulation. This a ords flexibility in the design of both voltage and current compensation loops to optimize performance in the end application.
