FAN6920MR Overview
The highly integrated FAN6920MR bines Power Factor Correction (PFC) controller and quasi−resonant PWM controller. Integration provides cost−effective design and reduces external ponents. For PFC, FAN6920MR uses a controlled on−time technique to provide a regulated DC output voltage and to perform natural power−factor correction.
