FL77944 Overview
The FL77944 is a direct AC line LED driver with a minimal number of external RC passive ponents. 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 dimming range, smooth dimming control and good dimmer patibility.
