FL7740 Datasheet (ON Semiconductor) - Constant-Voltage Primary-Side-Regulation PWM Controller

FL7740, Constant-Voltage Primary-Side-Regulation PWM Controller

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
