FAN6920MR - Integrated Critical-Mode PFC and Quasi-Resonant Current-Mode PWM Controller

General Description

The highly integrated FAN6920MR combines Power Factor Correction (PFC) controller and quasi-resonant PWM controller.

Integration provides cost-effective design and reduces 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 5µs tOFF for QR PWM Stage Internal 5ms Soft-Start for PWM Brownout Protection High / Low Line Over-Power Compensation Auto-Recovery Over-Current Protection Auto-Recovery Open-Loop Protection Externally Auto-Recovery Triggering (RT Pin) Adjustable Over-Temp.
