12 W Down Light ACLED Driver at High-Line


The FEBFL77944-L80H012A-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 FEBFL77944-L80H012A-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 FEBFL77944-L80H012A-GEVB suitable for high-efficiency LED lighting systems. The FEBFL77944-L80H012A-GEVB has dedicated DIM pin which can be used with analog or digital PWM dimming. The FEBFL77944-L80H012A-GEVB can also be used with a rheostat dimmer switch which is suitable for desktop or indoor lamps.

High wattage design of the FEBFL77944-L80H012A-GEVB can be implemented with multiple IC embedded in parallel for street lighting and down lighting applications.
