High 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 3 discrete level dimming using a two or three way switch. The design is based on the ON
Semiconductor NCP3065/3066.
