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 plies with the IEC1000−3−2 specification. Interleaved operation provides...
