FL77904 Overview
The FL77904 is a direct AC line LED driver with a minimal number of external RC passive ponents. In normal configuration, one resistor adjusts LED current for desired system luminance and another bypass capacitor provides a stable voltage to an internal biasing shunt regulator. The FL77904 provides phase-cut dimming with wide dimming range, smooth dimming control and good dimmer patibility.
