Designing a Constant Current LED Driver – Part 1

In the first episode of a complete video series, Steve begins the design of a constant current LED driver. This aim of this project is to create a four channel high power LED driver that can interface with an RS-485 or IEEE 802.15.4 MiWi network. This will allow control of multiple light fixtures or multicolour mood lights from one or more lighting controllers.

This first episode focuses on the design of the DC-DC converter which is optimised for use on a 24V power bus which a high switching frequency for small size. The components can be changed for other applications (different supply voltages or switching frequencies) using the concepts introduced in this video.
