FAN6920MR Datasheet | onsemi

Description 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. 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 pensation. Protection functions include secondary- side open- loop and over- current with auto- recovery protection; external auto- recovery triggering; adjustable over- temperature protection by the RT pin; and external NTC resistor, internal over- temperature shutdown, VDD pin OVP, and the 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).
