FEBFL77904-L82L08A-GEVB: 8 W AC LED Driver

The FEBFL77904-L82L08A-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 FEBFL77904-L82L08A-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 FEBFL77904-L82L08A-GEVB suitable for high-efficiency LED lighting systems. The high-power design of the FEBFL77904-L82L08A-GEVB can be achieved by embedding multiple ICs in parallel, which is suitable for streetlight and downlight applications.

The FEBFL77904-L82L08A-GEVB is a direct AC line LED driver with a 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.

The FEBFL77904-L82L08A-GEVB provides phase-cut dimming with wide dimming range, smooth dimming control and good dimmer compatibility. It achieves the high efficiency with high PF and low THD which makes the FEBFL77904-L82L08A-GEVB suitable for high-efficiency LED lighting systems.

High wattage design of the FEBFL77904-L82L08A-GEVB can be implemented with multiple IC embedded in parallel for street lighting and lighting down applications.
