Buck-boost power LED driver using PIC microcontroller
One traditional low-cost way of driving LED in electrical applications uses a resistor in series with the LED device. Although this driving scheme is simple and inexpensive, it suffers several disadvantages. The LED current can vary substantially over the battery voltage range even in normal operati...
