PWM Controller, Constant Voltage, Primary Side Regulation for Power Factor Correction

Favorite

Overview

The FL7740 provides accurate CV (Constant Voltage) regulation with differentiated dynamic function to minimize overshoot and undershoot of output voltage in line and load transient condition. Standby power is less than 0.3 W for smart lighting application and power factor is higher than 0.9 even half load condition when enabling PF optimizer for wide output powerscalability.
