FAN9611 Datasheet Interleaved Dual Bcm Pfc Controllers

Manufacturer: Fairchild (now onsemi)

Overview: FAN9611 — Interleaved Dual BCM PFC Controllers February 2013 FAN9611 Interleaved Dual BCM PFC.

General Description

The FAN9611 interleaved dual Boundary-ConductionMode (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.

Key Features

  • Sync-Lock™ Interleaving Technology for 180° Out-of-Phase Synchronization Under All Conditions.
  • Automatic Phase Disable at Light Load.
  • Dead-Phase Detect Protection.
  • 2.0 A Sink, 1.0 A Source, High-Current Gate Drivers.
  • High Power Factor, Low Total Harmonic Distortion.
  • Voltage-Mode Control with (VIN)2 Feedforward.
  • Closed-Loop Soft-Start with User-Programmable Soft-Start Time for Reduced Overshoot.
  • Minimum Restart Frequency to Avoid Audible Noise.
  • Maximu.
