Hello, My name is Sebastian Frentiu. I am an electronics engineer. I have over 9 years of experience in the automotive industry. I saw your add. I have the necessary skills to bring your idea to life. I have experience with DC-DC converters as well as battery chargers. I have designed a charging circuit before. It was very small. Due to a signed NDA, I can not show schematics or PCBs o the job. I can however tell you that I used a charging IC from Linear technology- LTC4160-1 and a boost from Texas Instruments- TPS61251. The project size was 25mm X 20mm. This is comparable to a memory stick. This particular charger had a max of 1.5Amps output. A 5V output and a dc voltage input. I have to clarify this: what is the desired input voltage on your project? And what is the desired output voltage? I assume the output voltage is 5V- usb compatible. I am new to Freelancer, but I do have valuable skills Skills that allow me to complete with success this project for you. And if you like my proposal, please write me back. Thank you for your time. Regards, Sebastian.
