Hi, Many years experience in electronics design and PCB layouts. While you give the possible voltage outputs from the solar panel you dont defne its power rating. Idealy this should be using MPPT techniques to maximise the enegery havesting form the panel. However if its simply a voltage converter you need I'd be happy to supply. Would you like the PCB in an Altium Designer or Eagle format? Did you have an enclosure in mind for the device? Any indicators? Regards and good luck with your project James Harrison-Smith

Designed in PADS/EAGLE will decide on the buck either from TI or LT. Done solar usb charger for campers/trekkers two years back.

Hi, I'm electronic engineer with more than 10 years of experience in electronic field: schematic, layout, firmware. A lot of projects are done and each of them have the power supply. So have the experience with power supply layout. For your task I suggest to use synchronous buck converter to have the high efficiency with switching frequency 2MHz or higher. What is the output current you need? At the output you will have schematic, layout (Gerbers and pcb), assembly files and BOM. Hope that I can be helpful for you. Regards, Alex

Hi there, There are a few clarification I need to do about the design first; What is the maximum current drawn from the circuit ? (since it's a charger the requirement may vary according to the phone you are charging) What is the minimum efficiency you expect ? (I can go for maximum efficiency possible but then you should state if there's any size or price limitation for the circuit) I presume you are certain about the 5.3V output, because it could harm some USB devices to receive 5.3V as the input. Please answer those questions so I can help you better. Thank You !

First of all it needs to determine a nominal charge current. The effectiveness of such type converters depends on the value of. What's the matter of you choice Linear Technology chips?
