The KA7526 provides simple and high performance active power factor correction. KA7526 is optimized for electronic ballast and low power, high density power supplies requiring a minimum board area, reduced component count and low power dissipation. Addition of internal R/C filter eliminates the need for an external R/C filter. Internal clamping of the error amplifier and multiplier outputs improves turn on overshoot characteristics and current limiting. Special circuitry has also been added to prevent no load runaway conditions. The output drive clamping circuit limits overshoot of the power MOSFET gate drive Independent of supply voltage, so that it greatly enhance the system reliability.
