Overview

Constant-Voltage Primary-Side-Regulation PWM Controller for Power Factor Correction FL7740 Description The FL7740 provides accurate CV regulation in the steady state 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 at half load condition when enabling PF optimizer for wide output power scalability.
Startup time is less than 0.
2 sec with built−in high voltage startup circuit and output voltage quickly reaches to the target CV level by loop gain transition technique during startup.
Various protections such as O...
