SA7527 Overview
The SA7527 provides simple and high performance active power factor correction. The SA7527 is optimized for electronic ballasts and low power and high-density power supplies which require minimum board size, reduced external ponents and low power dissipation. Because the R/C filter is included in the current sense block, the external R/C filter is not necessary.
