Datasheet

CAD Model

Overview

The FAN7527B provides simple and high-performance active Power Factor Correction (PFC). The FAN7527B is optimized for electronic ballasts and low鈥損ower, high-density power supplies that require minimum board size, reduced external components, and low power dissipation. Because the R/C filter is included in the current-sense block, an external R/C filter is not necessary. Special circuitry prevents no-load runaway conditions. Regardless of the supply voltage, the output drive clamping circuit limits the overshoot of the power MOSFET gate drive, which improves system reliability.
