LED Drivers
High Density Power Supply DC-DC Rail Outputs
Non-isolated Power Converters
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 1,360 W/in
3.
The full 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
PRM48BF480T400A00 and downstream VTM current
multiplier 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.
