FAN6921ML - Integrated Critical Mode PFC/Quasi-Resonant Current Mode PWM Controller
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.
For PFC, FAN6921ML uses a controlled on-time technique to provide a regulated DC output voltage and
