The FEBFL77944-L80H012A-GEVB is a direct AC line LED driver with a minimum number of external RC passive components. In normal configuration, one resistor is used to regulate the LED power and one capacitor is used to provide a stable voltage for the internal bias shunt regulator. The FEBFL77944-L80H012A-GEVB provides phase-cut dimming with a wide dimming range, smooth dimming control, and good dimmer compatibility. It achieves high efficiency, high PF, and low THD, which makes the FEBFL77944-L80H012A-GEVB suitable for high-efficiency LED lighting systems. The FEBFL77944-L80H012A-GEVB has a dedicated DIM pin that can be used for analog or digital PWM dimming. The FEBFL77944-L80H012A-GEVB can also be used with a rheostat dimming switch for desktop or indoor lamps. The high wattage design of the FEBFL77944-L80H012A-GEVB can be achieved by embedding multiple ICs in parallel, making it suitable for street lighting and downlight applications.
