Three-Channel Interleaved CCM PFC Controller FAN9673 Description 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.
