Overview
Power Factor Correction Controller FAN7527B 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 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.
Features • Internal Startup Timer • Internal R/C Filter Eliminates the Need for External R/C Filter • Precise Adjustable Output Over−Voltage Protection • Zero Current Detector • One Quadrant Multiplier • Trimmed 1.
5% Internal Band Gap Reference • Under−Voltage Lockout with 3 V of Hysteresis • Totem−Pole Output with High−State Clamp • Low Startup and Operating Current • 8−Pin SOP or 8−Pin DIP • These Devices are Pb−Free and are RoHS Compliant Applications • Electronic Ballast • SMPS DATA SHEET www.
