FAN480X PFC+PWM Combination Controller Application

FAN4800A / FAN4800C / FAN4801 / FAN4802 / FAN4802L

Introduction

The synchronization of the PWM with the PFC simplifies

the PWM compensation due to the controlled ripple on the

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 trailing-

edge duty cycle modulation, while the PFC uses leading-

edge modulation. This proprietary leading/trailing-edge

modulation technique can significantly reduce the ripple

current of the PFC output capacitor.

PFC output capacitor (the PWM input capacitor). In

addition to power factor correction, a number of protection

features have been built in to the FAN480X. These include

programmable soft-start, PFC over-voltage protection,

pulse-by-pulse current limiting, brownout protection, and

under-voltage lockout.

FAN4801/2/2L feature programmable two-level PFC

output to improve efficiency at light-load and low-line

conditions.

FAN480X is pin-to-pin compatible with FAN4800 and

ML4800, only requiring adjustment of some peripheral

components. The FAN480X series comparison is

summarized in the Appendix A.
