FAN9672 - Two-Channel Interleaved CCM PFC Controller
●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.
