FL77944 Datasheet (Fairchild Semiconductor) - Analog/PWM/Phase-cut Dimmable High Power LED Direct AC Driver

FL77944, Analog/PWM/Phase-cut Dimmable High Power LED Direct AC Driver

The FL77944 is a direct AC line LED driver with a minimal number of external RC passive components.

In normal configuration, one resistor is to adjust LED power, and one capacitor is to provide a stable voltage to an internal biasing shunt regulator.

The FL77944 provides phase-cut dimming with wide
