Datasheet Summary
Three-Channel Interleaved CCM PFC Controller
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.
An innovative channel management function allows slave channels to be loaded and unloaded...
