FL77905
Overview
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.
- The simplest Direct AC LED Driver with Only Two External RC Passive Components
- Wide AC Input Range : 90~305 VAC
- Three Integrated High-Voltage LED Constant Current Sinks of up to 75 mA (RMS) Capability
- TRIAC Dimmable (Leading/Trailing Edge)
- Rheostat Dimmable
- Analog/Digital PWM Dimming Function
- High Power Factor (above 0.98 in normal configuration)
- Adjustable LED Power with an External Current Sense Resistor
- Low Harmonic Content (THD under 20% in Normal Configuration)
- Compact SOIC 8-Lead Package
