Description

The FAN7527 provides simple and high performance active

power factor correction. FAN7527 is optimized for

electronic ballast and low power, high density power

supplies which require minimum board area reduced

component count and low power dissipation. Internal R/C

filter eliminates the need for an external R/C filter. Internally

clamping the error amplifier and multiplier outputs,

improves turn on overshoot characteristics and current

limiting. Special circuitry has also been added to prevent no

load runaway conditions. Independent of supply voltage, the

output drive clamping circuit limits overshoot of the power

MOSFET gate drive. This greatly enhances the system

reliability.
