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.

Key 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)
