FAN7527B
Power Factor Correction Controller
R/C Filter
Description
The FAN7527B provides simple and high performance
active power factor correction. The FAN7527B is optimized
for electronic ballasts and low power and high density power
supplies which require minimum board size, reduced
external components and low power dissipation. Because the
R/C filter is included in the current sense block, the external
R/C filter is not necessary. Special circuitry has also been
added to prevent no load runaway conditions. Regardless of
the supply voltage, the output drive clamping circuit limits
the overshoot of the power MOSFET gate drive. It greatly
enhances the system reliability.
