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 output voltage and to perform natural power factor correction. An innovative THD.
