Power LED's - Simplest Light With Constant-current Circuit: Here's a really simple and inexpensive ($1) LED driver circuit. The circuit is a "constant current source", which means that it keeps the LED brightness constant no matter what power supply you
Figure 3: Shunt FET circuit, with waveforms. Dimming with a shunt FET causes rapid shifts in the output voltage, to which the IC's control loop must respond in an attempt to keep the output current constant. As with logic-pin dimming, the faster the control loop, the better the response...
