NettetHere's how it works: U1, R1, and C1 generate a square wave. Adjusting R1 controls the duty cycle and frequency, and consequently, the brightness of the LED. When the output (pin 3) is low, Q1 is switched on. Current flows through the inductor, L1. This current grows as energy is stored in the inductor. Then, the output goes high. Nettet2. jun. 2015 · If you had a perfect voltage source with V = the LED's Vf at some current, and nothing else, the LED would pass that current. Of course, the bad news is if you're a little over (imperfect supply, drift due to temperature, etc.) your current might be significantly higher and blow out the LED, so it's not a good way to regulate things in …
