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

Description The highly integrated FAN6921ML combines a Power Factor Correction (PFC) controller and a QuasiResonant PWM controller. Integration provides cost effect design and allows for fewer external components. For PFC, FAN6921ML uses a controlled on-time technique to provide a regulated DC

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