Dual BCM PFC Controller

Overview of the Evaluation Board The FAN9611/12 interleaved dual Boundary-Conduction-Mode (BCM) Power-FactorCorrection (PFC) controllers operate two parallel-connected boost power trains 180º out of phase. Interleaving extends the maximum practical power level of the control technique from about
