Abstract
An LED driving circuit is provided. The LED driving circuit comprises a power converter, an LED loading, a detection resistor and voltage-division circuit. The power converter outputs a current to the LED loading according to a voltage difference between a reference voltage and a detected voltage. The current flows through the LED loading and the detection resistor. The voltage-division circuit connects to three end of the power converter, LED load and the detection resistor. Wherein, the detected voltage can be gotten from the voltage-division circuit.
