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 plies with the IEC1000−3−2 specification.
