FAN9611 Description
The FAN9611 interleaved dual Boundary−Conduction−Mode (BCM) Power−Factor−Correction (PFC) controller operates two parallel−connected boost power trains 180° out of phase. Interleaving extends the maximum practical power level of the control technique from about 300 W to greater than 800 W. Unlike the continuous conduction mode (CCM) technique often used at higher power levels, BCM offers inherent zero−current...
