FAN9612 - Interleaved Dual BCM PFC Controller

General Description

The FAN9612 Interleaved Dual Boundary-ConductionMode (BCM) Power-Factor-Correction Controller operates two parallel-connected boost power trains 180º out of phase.

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

Key Features

  • Low Total Harmonic Distortion, High Power Factor 180° Out of Phase Synchronization Automatic Phase Disable at Light Load 1.8A Sink, 0.8A Source, High Current Gate Drivers Trans-conductance (gM) Error Amplifier Voltage-Mode Control with (VIN) Feed Forward Closed-Loop Soft-Start with User-Programmable Soft-Start Time for Reduced Overshoot Minimum Restart Timer Frequency to Avoid Audibl.
