See other project, I have a setup that receives DMX512 data standard and drives LED's. It uses Raspberry Pi, the raspberry pi uses SPI to connect to a board (using a Sprakfun for prototyping) which outputs PWM. I need to step up that PWM to approx 24v 1amp to drive my led's I need someone to work with me to design the best solution for this.

Hi, My name is Junaid and I am an experienced electrical engineer. My expertise are in designing of driver circuits. I have designed many motor drivers, relay drivers and high power led drivers. What i get from your requirements is that you have PWM signal but that signal can not drive your LEDs and you need to step your PWM signal up to 24V with 1A current capacity. I will design highly efficient circuit with minimum heating losses. I need details of your LEDs and PWM frequency to choose right components for the job. Please contact for more details and to know about my skills and my portfolio. Looking forward to hearing from you. Thanks a million.

Hello Sir! It would be nice to have more information about the PWM part of this project, certainly the physical part of LED driver to suggest something. Which programming language used to create the application of LED driving? And there are more questions appear. Can we discuss them on chat? PS. So, I found some answers on your other project. You work with C++ and the changes you've described there is the PWM. Which version of Raspberry do you have? Depending on hardware version differences may appear because of different processors are used.

Hello, I am interested to work with your project. To step up to 24V 1A from Raspberry PI 5V it should draw about 5 to 6 Amps from 5V supply. I doubt you have such power supply available. More feasible seems to use 24V supply for PWM leds and then step down 5V for Raspberry PI use if necessary. I have raspberry PI and some DMX devices to do some testing. Do you need just a schematic or prototype as well? I would prefer to work on milestone basis, by setting some goals like schematic, layout and prototype, or other project steps. Best regards and let me know any questions.

I am an electrical engineer in Australia with an interest in power electronics. It should only take an hour on the phone and/or Skype to work out a solution for you LED driver. Then maybe another hour to find specific parts and produce a schematic.
