FL77904 - Phase-cut Dimmable Compact LED Direct AC Driver

General Description

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.

Key Features

  • 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.
