DESCRIPTION
The VI Chip^® PRM^® Regulator is a high efficiency
converter, operating from a 38 to 55 Vdc input to generate
a regulated 5 to 55 Vdc output. The ZVS Buck – Boost
topology enables high switching frequency (~1 MHz)
operation with high conversion efficiency. High switching
frequency reduces the size of reactive components
enabling power density up to 1,300 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
PRM48BH480T200B00 and downstream VTM^®
transformer minimize distribution and conversion losses in
a high power solution.
An external control loop and current sensor maintain
regulation and enable flexibility both in the design of
voltage and current compensation loops to control of
output voltages and currents.
