Overview 

Power circuit is one of the most important in an electric device. They are a source that supplies power for devices working. Electric devices usually work with low DC supply as 3.3v, 12v, ... but the electrical grid is 120V AC, therefore power circuit will convert AC into DC for electric devices.

Purpose

LED Driver uses a Hybrid DC-DC converter for convert voltage from 120v into 12v with high efficiency, supply power for LED. The circuit can change the output voltage from 0v to 20V.

Development Direction 

Implement closed-loop for the next manufacture and further optimize components.
