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

General Description

The highly integrated FAN6920MR combines Power Factor Correction (PFC) controller and quasi-resonant PWM controller. Integration provides cost-effective design and reduces external components.For PFC, FAN6920MR 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, FAN6920MR can reduce input current distortion at zero-crossing duration to improve THD performance.For PWM, FAN6920MR provides several functions to enhance the power system performance: valley detection, green-mode operation, and high / low line over-power compensation. Protection functions include secondary-side open-loop and over-current with auto-recovery protection; external auto-recovery triggering; adjustable over-temperature protection by RT pin; and external NTC resistor, internal over-temperature shutdown, VDD pin OVP, and DET pin over-voltage for output OVP, and brown-in / out for AC input voltage UVP.The FAN6920MR controller is available in a 16-pin small-outline package (SOP).
