Pre-Regulator Module (PRM)
PRODUCT DESCRIPTION
The Vâ¢I Chip Pre-Regulator Module (PRM) is a very efficient non-isolated regulator capable of both boosting and bucking a wide range input voltage. It is
specifically designed to provide a controlled Factorized Bus distribution voltage for powering downstream Vâ¢I Chip Voltage Transformation Modules
(VTMs)â fast, efficient, isolated low noise Point-of-Load (POL) converters.
PRMs feature a unique "Adaptive Loop" compensation feedback: a single wire alternative to traditional remote sensing and feedback loops that enables
precise control of an isolated POL voltage without the need for either a direct connection to the POL or for noise sensitive, bandwidth limiting, isolation
devices in the feedback path.
