The FL77905 is a direct AC line LED driver with 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.
It achieves high efficiency with high PF and low THD which makes the FL77905 suitable for high-efficiency LED lighting systems. The FL77905 can also be used with a rheostat dimmer switches which are suitable for desktop or indoor lamps.
The FL77905 has a dedicated DIM pin which is designed to be used with analog or digital PWM dimming.
The simplest Direct AC LED Driver with Only Two External RC Passive Components
Wide AC Input Range: 90~305 VAC
High Power Factor (above 0.98 in normal configuration) Low Harmonic Content (THD under 20% in normal configuration)
Low Flicker Index by Self Valley Fill with No Degradation of PF and THD
Adjustable LED Power with an External Current Sense Resistor
