Description
The VI BRICK PRMis 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” from 26 to 55 V. VI BRICK PRMs can be used stand-alone as non-isolated voltage regulators or combined with VI Brick VTMs for a complete isolated, DC-DC solution with higher efficiency and power density.The VI BRICK VTM provides point-of-load, fixed ratio voltage transformation with extremely fast transient response and isolation to 2,250 Vdc. These modules utilize the technical advantages of Factorized Power™ including high density and efficiency, low noise operation, fast transient response, and elimination of bulk capacitance at the point of load (POL).
They also provide the flexibility and scalability to design for unique requirements based on multiple outputs, power levels and physical layout. The rugged aluminum baseplate enclosure and through-hole pin connection provide a simplified platform for mounting and thermal management.
