FAN4810

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 specification. 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 overvoltage 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.
