Overview of FL7921RMX
The FL7921R is a cutting-edge product that merges a Power Factor Correction (PFC) controller with a Quasi-Resonant PWM controller for optimal performance and efficiency. By integrating these two essential functions, this device streamlines the design process and reduces the need for numerous external components. The FL7921R employs a controlled on-time technique for PFC, ensuring a stable DC output voltage and improved power factor correction. What's more, an innovative THD optimizer works to reduce input current distortion, particularly during zero-crossing duration, thereby enhancing overall THD performance. Notably, the PFC function remains active regardless of the PWM stage load condition, ensuring high power factor even at lighter loads. On the PWM side, the FL7921R offers a range of functions aimed at boosting power system performance, such as valley detection, green-mode operation, and high/low line over-power compensation. It also boasts various protection features, including secondary-side open-loop and over-current protection with auto-recovery, adjustable over-temperature protection, and numerous others to safeguard the device under different circumstances
