General Description
The FAN4810 is a controller for power factor corrected,
switched mode power supplies. The FAN4810 includes
circuits for the implementation of leading edge, average
current, “boost” type power factor correction and results in a
power supply that fully complies with IEC1000-3-2 specifi-
cation. It also includes a TriFault Detect™ function to help
ensure that no unsafe conditions will result from single
component failure in the PFC. Gate-driver with 1A
capability minimizes the need for external driver circuit.
Low power requirements improve efficiency and reduce
component costs. The PFC also includes peak current
limiting, input voltage brownout protection and a over-
voltage comparator shuts down the PFC section in the event
of a sudden decrease in load. The clock-out signal can be
used to synchronize down-stream PWM stages in order to
reduce system noise.
