Hi,
As I understand your project, it is to develop a constant current driver for high power LEDs. You require high power, high efficiency, 16-bit precision, and 8 A @ 12 V output.
My skills are in embedded systems design and power electronics. I have experience with high current power converters. My skills allow me to finish the project in a relatively short period of time for a relatively low cost. My 20-workday estimate is due to the full week turnaround time for PCB manufacturing, but that can be shortened if required.
If you accept my bid, I will deliver:
1. Full schematic
2. Design materials, simulations, and test results
3. Bill of Materials with suppliers and part numbers
4. PCB design and gerber files for manufacturing
5. Firmware and control software source code
6. Functional prototype
I am excited about this project and I am looking forward to hearing from you.
