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.
