FL77904
Overview
The FL77904 is a direct AC line LED driver with a minimal number of external RC passive components. In normal configuration, one resistor adjusts LED current for desired system luminance and another bypass capacitor provides 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
- Four Integrated High-Voltage LED Constant Current Sinks of up to 75 mA RMS Input Current Capability
- 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
- TRIAC Dimmable (Leading/Trailing Edge)
- Rheostat Dimmable Flexible LED Forward Voltage Configuration
- Power Scalability with Multiple Driver ICs
- Over-Temperature Protection (OTP)
