产品概述
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. The FAN9673 also incorporates a variety of protection functions including peak current limiting, input voltage brown out protection and TriFault detect function.
