FAN6921ML - Integrated Critical Mode PFC/Quasi-Resonant Current Mode PWM Controller

Datasheet Summary

Description

The highly integrated FAN6921ML combines a Power Factor Correction (PFC) controller and a QuasiResonant PWM controller.

Integration provides costeffect design and allows for fewer external components.

Features

  • Integrated PFC and Flyback Controller.
  • Critical Mode PFC Controller.
  • Zero-Current Detection for PFC Stage.
  • Quasi-Resonant Operation for PWM Stage.
  • Internal Minimum tOFF 8 µs for QR PWM Stage.
  • Internal 10 ms Soft-Start for PWM.
  • Brownout Protection.
  • H/L Line Over-Power Compensation (OPC).
  • Latched Protection (FB Pin)  Over-Power/ Overload Protection  Short-Circuit Protection  Open-Loop Protection.
  • Externally Latch Triggering (RT Pin).
  • Adjus.
