Integrated Critical Mode PFC and Quasi-Resonant Current Mode PWM Controller
Description The highly integrated FAN6921MR bines Power Factor
Correction (PFC) controller and Quasi- Resonant PWM controller. Integration provides cost effect design and allows for fewer external ponents.
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...
