FAN9673 Datasheet Three-channel Interleaved Ccm Pfc Controller

Manufacturer: onsemi

Overview: Three-Channel Interleaved CCM PFC Controller FAN9673.

General 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 substantial reduction in the input and output ripple currents and the conducted EMI filtering bees easier and cost effective.
