Designing a Constant Current LED Driver – Part 2

In this video Steve interfaces the DC-DC converter circuit with a Microchip dsPIC33FJ16GS502 microcontroller to create a microcontroller-based constant current LED driver. The dsPIC33FJ16GS502 microcontroller has four analogue comparators which allow expandability to 4 independent constant current channels. http://www.youtube.com/watch?v=Jcble4aiNlw

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 […]
