Hi,
I have experience in designing 12V, 10A SPMS based power supply, and I can surely design you according to your requirements. You can check the PCB design of 12V, 10A power supply in my portfolio.
If you feel interested then lets discuss further in chat. Client satisfaction is my first priority, as I believe a satisfied client comes back for another work. Looking forward to work with you. Thank you.
Best Regards,
Waseem
