AN-6982

Power Factor Correction Converter Design with FAN6982

Introduction

The FAN6982 is a 14-pin, Continuous Conduction Mode

(CCM) Power Factor Correction (PFC) controller IC, that

employs leading-edge modulation for average current

control and has a number of advanced features for better

performance and reliability. The variable output voltage

function (range function) reduces PFC output voltage at

light-load and low-line conditions to improve light-load

efficiency, but can be also easily disabled using EN pin.

The RDY signal can be used for power-on sequence

control of the downstream DC/DC converter. A TriFault

Detect™ function helps reduce external components and

provides full protection for feedback loops such as open,

short, and over voltage. FAN6982 also includes PFC soft-

start, peak current limiting, line feed-forward, and input

voltage brownout protection.

This application note describes the theory of operation and

step-by-step design considerations for a power factor

correction power supply using the FAN6982 controller. A

typical application circuit is shown in Figure 1, where the

supply voltage, V_DD, is supplied from a standby auxiliary

power supply and the supply voltage for the downstream

converter is controlled by the RDY pin.
