Overview
The highly integrated FL7921R combines a Power Factor Correction (PFC) controller and a QuasiResonant PWM controller. Integration provides costeffect design and allows for fewer external components. For PFC, FL7921R uses a controlled on-time technique to provide a regulated DC output voltage and to perform natural power factor correction. An innovative THD optimizer reduces input current distortion at zerocrossing duration to improve THD performance. The PFC function is always on regardless of the PWM stage load condition to ensure that high PF can be achieved at light load condition. For PWM, FL7921R provides several functions to enhance power system performance: valley detection, green-mode operation, high / low line over-power compensation. Protection functions include secondaryside open-loop and over-current with auto-recovery protection, external recovery triggering, adjustable overtemperature protection through the RT pin and external NTC resistor, internal over-temperature shutdown, VDD pin OVP, DET pin over-voltage for output OVP, and brown-in / out for AC input voltage UVP. All protections are auto recovery mode except PWM current sense pin open protection. The FL7921R controller is available in a 16-pin, smalloutline package (SOP).
