Description
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 components. The FAN7535 PFC control block to reduce the input current THD lower than conventional CRM boost PFC methods. An innovative Active Zero Voltage Switching (AZVS) block reduces the swtiching power loss. A dedicated timing section in the FAN7535 allows the user set the necessary parameters for proper lamp preheat and ignition.
