ºìÌÒÊÓƵ

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. 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.

  • LED Lighting – Mid Power- Analog/PWM dimming
  • LED Lighting – Mid Power – Phase-cut dimming
  • LED Lighting – Low Power – Phase-cut dimming

  • The simplest Direct AC LED Driver with Only Two External RC Passive Components
  • Wide AC Input Range: 90~305 VAC
  • Analog/PWM Dimming
  • 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
  • Rheostat Dimmable Flexible LED Forward Voltage Configuration
  • Power Scalability with Multiple Driver ICs
  • Over-Temperature Protection (OTP)
