Description

General part information

FAN9673 Series

The FAN9673 is an interleaved three-channel Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC intended for PFC pre-regulators. Incorporating circuits for the implementation of leading edge, average current, and "boost"-type power factor correction; the FAN9673 enables the design of a power supply that fully complies with the IEC1000-3-2 specification. Interleaved operation provides substantial reduction in the input and output ripple currents and the conducted EMI filtering becomes easier and cost effective.An innovative channel management function allows the power level of the slave channels to be loaded and unloaded smoothly according to the setting voltage on the CM pin, improving the PFC converter’s load transient response.The FAN9673 also incorporates a variety of protection functions, including: peak current limiting, input voltage brown out protection, and TriFault Detect™ function.
