3 A © Product Description The PRM™ regulator 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 VTM™ current multiplier — fast, efficient, isolated, low noise Point-of-Load (POL) converters.
In combination, PRM modules and VTM modules form a complete DC-DC converter subsystem offering all of the unique benefits of Vicor’s Factorized Power ArchitectureTM (FPATM) : high density and efficiency; low noise operation; architectural flexibility; extremely fast transient response; and elimination of bulk capacitance at the Point-of-Load (POL).
In FPA systems, the POL voltage is the product of the Factorized Bus voltage delivered by the PRM module and the "K-factor" (the fixed voltage transformation ratio) of a downstream VTM module.
The PRM regulator controls the Factorized Bus voltage to provide regulation at the POL.
Because VTM modules perform true voltage division and current multiplication, the Factorized Bus voltage may be set to a value that is substantially higher than the bus voltages typically found in "intermediate bus" systems, reducing distribution losses and enabling use of narrower distribution bus traces.
A Military PRM module-VTM module chip set can provide up to 100 A or 115 W at a FPA system density of 169 A/in3 or 195 W/in3 — and because the PRM module can be located, or "factorized," remotely from the POL, these power densities can effectively be doubled.
