Analog / PWM / Phase-cut Dimmable Compact LED Direct AC Driver

The FL77905 is a direct AC line LED driver with 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. It achieves high efficiency with high PF and low THD which makes the FL77905 suitable for high-efficiency LED lighting systems. The FL77905 can also be used with a rheostat dimmer switches which are suitable for desktop or indoor lamps.The FL77905 has a dedicated DIM pin which is designed to be used with analog or digital PWM dimming.
