DC-DC Buck Converter
Input Voltage: 60~140V (input voltage will be variable)
Input Current: 10A max (input current will be variable)
Output: 26~[url removed, login to view] (Must be regulated by using PWM Frequency)
Output Current: 40A Max.
Design the Efficiency Curve and specially for 80V and 120v
Design the PCB Schematic
Design the PCB Layout
Export the design to GERBER and create a BOM
Let me know the operating frequency and min. max. duty cycles.
Converter must operate with very low loss.

Ian was very patient throughout the project as I was constantly either changing my mind or requiring guidance to avoid future problems. Ian was very open to suggestions and is more than happy to accept feed back during the project to help me get exactly what I was after. The project was delivered on budget and on time with everything I requested provided without issue. He even over engineered the design to give me something even better than I was hoping for! Ian was very clear and very descriptive with any technical explanations he provided and made sure that I understood what he was doing. Any time he had to change specifications or redesign due to any issues he encountered he made sure to discuss them over with me first and explained why it would not work and how the new solution would benefit me. I will definitely hire Ian and Cloudline again! Thanks Ian :-)
