DATA SHEET www.onsemi.com Interleaved Dual BCM PFC Controllers FAN9611 SOIC−16, 150 mils CASE 751BG−01 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 switching of the boost diodes, which permits the use of less expensive diodes without sacrificing efficiency. Furthermore, the input and output filters can be smaller due to ripple current cancellation and effective doubling of the switching frequency.
