FAN7527BMX Datasheet

Power Factor Correction - PFC


The FAN7527BMX 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. FAN7527BMX Features • Internal start-up timer• Internal R/C filter eliminates the need for an external R/C filter• Very precise adjustable output over voltage protection• Zero current detector• One quadrant multiplier• Trimmed 1.5% internal band gap reference• Under voltage lockout with 3V of hysteresis• Totem pole output with high state clamp• Low start-up and operating current• 8-Pin DIP or 8-Pin SOP
