DATA SHEET www.onsemi.com Integrated Critical Mode PFC and Quasi-Resonant Current Mode PWM Controller FAN6921MR Description The highly integrated FAN6921MR combines Power Factor Correction (PFC) controller and Quasi−Resonant PWM controller. Integration provides cost effect design and allows for fewer external components. For PFC, FAN6921MR uses a controlled on−time technique to provide a regulated DC output voltage and to perform natural power factor correction. With an innovative THD optimizer, FAN6921MR can reduce input current distortion at zero−crossing duration to improve THD performance. For PWM, FAN6921MR provides several functions to enhance the power system performance: valley detection, green−mode operation, high / low line over power compensation.
