As well as giving you fast proof-of-concept for your high power lighting designs, our solution offers several key benefits.
Connecting directly to the mains, our AC/DC converter reference design for high-power LED strings distributes power to local or distributed light engines. Optimized for driving 25 high-power LEDs in series at 350 mA (giving a total VF(LED) of approximately 70 V), it can be easily adapted for different voltage and / or current requirements.
The reference design supports LED dimming through current reduction, for example, via a logarithmic variable resistor (potentiometer). This allows dimming to less than 2% to be achieved.
