FAN7527B Power Factor Correction Controller Features Description Internal Startup Timer Precise Adjustable Output Over-Voltage Protection Internal R/C Filter Eliminates the Need for External R/C Filter Zero Current Detector One Quadrant Multiplier Trimmed 1.5% Internal Band Gap Reference Under-Voltage Lockout with 3 V of Hysteresis The FAN7527B provides simple and high-performance active Power Factor Correction (PFC). The FAN7527B is optimized for electronic ballasts and low–power, highdensity 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.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol VCC Parameter Min.
