Product Overview

The FAN9673QX is a interleaved three-channel continuous conduction mode (CCM) power factor correction (PFC) controller in 32 pin LQFP package. 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. An innovative channel management function allows the power level of the slave channels to be loaded and unloaded smoothly according to the setting voltage on the CM pin, improving the PFC converter's load transient response. The FAN9673 also incorporates a variety of protection functions including peak current limiting, input voltage brown out protection and TriFault detect function.
  • Average current mode control
  • PFC slave channel management function
  • Programmable operation frequency range from 18KHz to 40KHz or 55KHz to 75KHz
  • Programmable PFC output voltage
  • Two current limit functions
  • Sag protection
  • Programmable soft-start
  • Undervoltage lockout (UVLO)
  • Differential current sensing
