The FL7921RMX from On Semiconductor is a highly integrated controller combining Power Factor Correction (PFC) and Quasi-Resonant PWM functionalities. This integration reduces the need for external components, leading to a more cost-effective design.
For PFC, it utilizes a controlled on-time technique for regulated DC output and natural power factor correction, with an innovative THD optimizer to improve performance. The PFC function remains active regardless of the PWM stage load, ensuring high PF even at light loads.
The PWM stage offers features like valley detection, green-mode operation, and over-power compensation. Protection functions include auto-recovery for open-loop, over-current, and over-temperature conditions, along with VDD and output over-voltage protection, and brown-in/out protection for AC input voltage.
This controller is available in a 16-pin SOIC package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TA).
