ssr01 pth versionHigh power LEDs require a constant current power supply for optimal operation. GLED1 is designed to drive 10W white LEDs (9 diodes in series) from a 12V or 24V supply. The board can be used down to 3V but the maximum output power will be reduced in this case. The design supports discrete level dimming using a two or three way switch or continuous control using a PWM signal. The design is based on the ON Semiconductor NCP3065/3066.


  • wide input voltage (3-26V)
  • supports strings of 3 to 10 leds in series
  • PWM dimming when using NCP3066
  • high efficiency
