FEBFL77905-L83H08A-GEVB: 8W AC LED Driver

The FEBFL77905-L83H08A-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 FEBFL77905-L83H08A-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 FL77905 suitable for high-efficiency LED lighting systems. The FL77905 has a dedicated DIM pin that can be used for analog or digital PWM dimming. The high power design of the FEBFL77905-L83H08A-GEVB can be achieved by embedding multiple ICs in parallel, which is suitable for streetlight and downlight applications.

FEBFL77905-L83H08A-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 FEBFL77905-L83H08A-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 FL77905 suitable for high-efficiency LED lighting systems. The FL77905 has a dedicated DIM pin which can be used with analog or digital PWM dimming.

High wattage design of the FEBFL77905-L83H08A-GEVB can be implemented with multiple IC embedded in parallel for street lighting and down lighting applications.
