DescriptionThe 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.
