Pre-Regulator Module (PRM) PRODUCT DESCRIPTION The V•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 V•I Chip Voltage Transformation Modules (VTMs)— 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.
