com Integrated Critical Mode PFC and Quasi-Resonant Current Mode PWM Controller FAN6921BMR Description The highly integrated FAN6921BMR combines Power Factor Correction (PFC) controller and Quasi−Resonant PWM controller.
Integration provides cost effect design and allows for fewer external components.
For PFC, FAN6921BMR 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, FAN6921BMR can reduce input current distortion at zero−crossing duration to improve THD performance.
For PWM, FAN6921BMR provides several functions to enhance the power system performance: valley detection, green−mode operation, high / low line over power compensation.
FAN6921BMR provides many protection functions as well: secondary−side open−loop and over−current with auto recovery protection, external latch triggering, adjustable over−temperature protection by RT pin and external NTC res...
