FAN9611 Datasheet PDF - Fairchild

Description

●The FAN9611/12 family of interleaved dual Boundary Conduction-Mode (BCM) Power-Factor-Correction (PFC)

●controllers operate two parallel-connected boost power trains 180° out of phase.Interleaving extends the

●maximum practical power level of the control technique from about 300W to greater than 800W.
