【文字介紹】

FAN9673 is an interleaved two-channel Continuous Conduction Mode(CCM) Power Factor Correction (PFC) controller IC intended for PFC pre-regulators. Incorporating circuits for leading edge, average current, and boost-type power factor correction; the FAN9672 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 simpler and cost effective.
