Greetings Art, Alok here again. Since your budget is tight, I will give you a schematic and PCB design for this specs - 43V-5A to 19V-5A (no extra protection or anything) which you can get it manufactured and assembled on your own. I will charge you $750. Let me know if this works for you. T & R Alok Pugalia

I am assuming, the requirement of this job is to build a physical power supply which can convert 43V to 19V/5A power supply. So here I am to assist you in building the power supply. I am based in India and can easily product this nice piece of power supply which will convert the 43V to 19V/5A power supply. The input current will be somewhere around 2-2.5A Amp to deliver 5Amp to the output. It will be switched mode power supply so the efficiency of the product will be more than 80-85% in order to produce less heat. Please note that the price I mentioned here includes making prototype on a nice looking home brew Printed Circuit Board with all through hole components. It will be compact and my estimation would be 75mm x 60mm board can hold everything nicely. ALSO PLEASE NOTE that my bid doesnt include shipping cost which may be somewhere around $100 bucks if sent though FedEx or any front line courier. I have sent many prototypes to US before and would be a pleasure to work on this as well. Thanks and do let me know if you want to avail my service in this regard. Thanks very much. Regards... Roy

Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for an electronics engineer capable of designing a custom solar charger for Li-Ion batteries to all stated requirements. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Proposal for solution 3. Block diagram of proposed solution 4. Discussion of proposed solution 5. Schematic drafts based on proposed solution 6. Component library creation 6.1 Schematic symbol library creation 6.2 Footprint library creation 7. Schematic drawings 8. Review of schematic drawings 9. Layout design 9.1 Components placement and arrangement 9.2 Components routing 9.3 Review of final layout design 10. Design rule check 11. Final check, verification and validation 12. Production files (GERBER, NC DRILL, ASM, PICK & PLACE, STEP, BOM, SCH, 2D mechanical) Your project will be carried out on Altium Designer and Autodesk Inventor. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for you time.
