Description
The FAN6982 is a 14-pin, Continuous Conduction Mode
(CCM) PFC controller IC 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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.
