FL77905 Description
The FL77905 is a direct AC line LED driver with 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 FL77905 provides phase-cut dimming with wide dimming range, smooth dimming control and good dimmer patibility.
