Overview

Two-Channel Interleaved CCM PFC Controller FAN9672 Description The FAN9672 is an interleaved two−channel Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC intended for PFC pre−regulators.
Incorporating circuits for leading edge, average current, and “boost”−type power factor correction; the FAN9672 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 simpler and cost effective.
An innovative channel−management function allows slave channels to be loaded and unloaded smoothly in lower power−level conditions according to setting voltage on the CM pin, improving the PFC converter’s load transient response.
The FAN9672 also incorporates a variety of protection functions, including: peak current limiting, input voltage brownout protection, and TriFault Detect function.
