Part Name(s) : AN-8027 FCP20N60S Fairchild
Fairchild Semiconductor
Description : FAN480X PFC+PWM Combination Controller ApplICation View

Introduction
This applICation note describes step-by-step design considerations for a power supply using the FAN480X Controller. The FAN480X combines a PFC Controller and a PWM Controller. The PFC Controller employs average current mode control for Continuous Conduction Mode (CCM) boost converter in the front end. The PWM Controller can be used in either current mode or voltage mode for the downstream converter. In voltage mode, feed-forward from the PFC output bus can be used to improve the line transient response of PWM stage. In either mode, the PWM stage uses conventional trailingedge duty cycle modulation, while the PFC uses leadingedge modulation. This proprietary leading/trailing-edge modulation technique can signifICantly reduce the ripple current of the PFC output capacitor.
