FL77905 是一款直连交流线路 LED 驱动器,外部 RC 无源部件数量减到最少。在正常配置中,一个电阻用于调节 LED 功率,一个电容器用于为内部偏置分路稳压器提供稳定电压。 FL77905 实现了高能效,具有较高功率因数和低 THD,因此适用于高能效 LED 照明系统。FL77905 还可用于可变电阻器调光开关,适用于台灯或室内灯。FL77905 具有专门的 DIM 引脚,可用于模拟或数字 PWM 调光。
特性
 
  • 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)
应用
  • LED 照明 — 中功率 — 模拟/PWM 调光
