Evaluation Board | FEBFL77905-L83H08A-GEVB
8W AC LED Driver
概览
The 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.
