Method and Apparatus for Driving LED using low-cost dsPIC

摘要

A method and apparatus for driving an LED using a low-cost dsPIC are presented. The LED driving method using the low-cost dsPIC proposed in the present invention includes a step in which the digital control IC receives the output voltage and the output current from the power stage, and generates a signal for driving the power stage using the preset programming of the digital control IC And outputting a signal for driving the power stage at the time when the current of the transformer of the power stage is '0'.
