FAN7527B Overview
The FAN7527B provides simple and high−performance active Power Factor Correction (PFC). The FAN7527B is optimized for electronic ballasts and low power, high−density power supplies that require minimum board size, reduced external ponents, and low power dissipation. Because the R/C filter is included in the current−sense block, an external R/C filter is not necessary.
