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.
