Full-Chip PRM

Non-isolated, regulator
320 W in 1.1 in² package
ZVS buck-boost topology
ZVS, >1 MHz switching frequency
Power density >1,100 W/in³

Full / Half-Chip VTM

Isolated, voltage transformer
Up to 130 A in 1.1 in²
ZVS, ZCS, >1 MHz switching frequency

The PRM is a very efficient non-isolated regulator capable of both boosting and bucking a wide range input voltage and provides a regulated, adjustable output voltage or "Factorized Bus". PRMs can be used stand-alone as non-isolated voltage regulators or combined with VTMs for a complete isolated, DC-DC solution with higher efficiency and power density. The VTM provides point-of-load, fixed ratio voltage transformation with extremely fast transient response and isolation to 2,250 Vdc. Additional features include:

Small footprint
Low weight
Bulk capacitance elimination
Through hole option available, except in half-chip package

Full-chip and half-chip models are compatible with standard pick-and-place and surface mount assembly processes.

MIL-COTS MV036 Series

The PRM Constant Current (CC) Demonstration Board is suitable for light-emitting diode (LED) applications such as street & stadium lighting, high-end projectors, active outdoor advertising and architectural installations. The board provides a precisely regulated current as required for direct drive multi-LED applications where the intensity and brightness are controlled by regulating the current through the LEDs.

The PRM CC board can be used to provide adjustable current up to 240 W (5 A at 48 V) when employed as a standalone non–isolated source or can be combined with a range of VTM™ voltage transformers to provide an adjustable isolated current up to 100 A.

The board has Kelvin connections for measuring the efficiency of the V•I Chip components independent of load losses. Oscilloscope probe jacks are available for measuring output voltage, including output voltage ripple. The board is equipped with fused PRM inputs, system enable and disable, and option for mounting a V•I Chip pushpin heat sink. For more details, see the Constant Current (CC) Demonstration Board User’s Guide (UG: 007) and Application Note:018, Providing a Constant Current for Powering LEDs using the PRM and VTM.
