FAIRCHILD AN6012 Manual
The document describes the FAN7528, an active power factor correction (PFC) controller designed for boost PFC applications operating in critical conduction mode (CRM). It operates in voltage mode, eliminating the need for a rectified AC line voltage sensing network to save power. The controller features a dual output control function that adjusts the internal reference voltage based on the AC line voltage range (100Vac or 220Vac) without direct sensing, optimizing output voltage for low and high line conditions.
