Power Factor Controller (PFC) CCM, PFC-Ready Signal, Brown Out Protection, Programmable 2 Level Output Voltage

Favorite

Overview

The FAN6982 is a 14-pin, Continuous Conduction Mode (CCM) power factor correction controller intended for Power Factor Correction (PFC) pre-regulators. The FAN6982 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 the IEC1000-3-2 specification.A TriFault Detect™ function helps reduce external components and provides full protection for feedback loops such as open, short, and over voltage. An over-voltage comparator shuts down the PFC stage in the event of a sudden load decrease. The RDY signal can be used for power-on sequence control. The EN function can choose to enable or disable the range function. FAN6982 also includes PFC soft-start, peak current limiting, and input voltage brownout protection.
