Description
SA7527STR is a power factor correction controller that provides simple and high-performance active power factor correction. It 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. The external R/C filter is not necessary because the R/C filter is included in the current sense block. 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.
