PFM Applications
The block diagram below shows a 400 Watt PFC front end with two PFMs in a parallel configuration. Higher power can be achieved by adding
additional PFMs.

— Typical application using Factorized Power Architecture (FPA)
The block diagram below shows an example of a Factorized Power system from the wall plug to the point-of-load. The PFM directly regulates a
primary high power output through a VTM to provide voltage division. A secondary output is independently regulated with a PRM. Auxiliary
outputs are derived through a VI Chip Bus Converter Module (BCM) and non-isolated POL converters.
