VI Chip PRM® ModulePoint-of-load, Buck-Boost regulation Factorized Power
Architecture 500 W in 1.1 in² at 97% Efficiency

Vicor's VI Chip PRM module is a very efficient non-isolated regulator capable of both bucking and boosting a wide range input voltage and provides a regulated, adjustable output voltage. PRMs can be used stand-alone as non-isolated voltage regulators or combined with VTMs for a complete isolated, DC-DC solution with high efficiency and power density.

High Density

• Up to 1,700 W/in³ with 500 W in 1.1in² package

Wide Vin Optimized for 48 Vout

• 24 Vin, 18 – 36 Vin range
• 36 Vin, 18 – 60 Vin range
• 45 Vin, 38 – 55 Vin range
• 48 Vin, 36 – 75 Vin range

Simple to Use

• Integrated package
• Minimal external components

High Efficiency

• Full-chip up to 500 W at 97.8%
• Half-chip up to 250 W at 96.7%

Flexible

• Regulation: Remote sense, local loop, adaptive loop
• Parallel capable
