FAN7535 Overview
FAN7535 provides simple, high-performance, active power factor correction (PFC), and ballast control. The FAN7535 is optimized for all kinds of fluorescent lamps, which require minimum board area and reduced external ponents. The FAN7535 PFC control block to reduce the input current THD lower than conventional CRM boost PFC methods.
