FL7921R - PWM Lightning Controller

The highly integrated FL7921R combines a Power Factor Correction (PFC) controller and a Quasi *Resonant PWM controller.

Integration provides cost effect design and allows for fewer external components.

For PFC, FL7921R uses a controlled on *time technique to provide a regulated DC outp
