FAIRCHILD AN4107 Manual
The document provides an introduction to the FAN7527, an active power factor correction (PFC) controller designed for boost applications. It operates in critical conduction mode by turning on the MOSFET when inductor current reaches zero and turning it off based on a desired input current reference voltage.
