Datasheet Summary
Power Factor Correction Controller
Description The FAN7527B provides simple and high- performance active
Power Factor Correction (PFC). The FAN7527B is optimized for electronic ballasts and low- power, high- density power supplies that require minimum board size, reduced external ponents, 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.
