TIDA-01623: Simplify the design

Aquiel Godeau

Part Number: TIDA-01623

Hi,

I was wondering if there was a way to simplify the design for the TIDA-01623 reference design. I want to remove the USB component and have the power be directly connected to a gateway. How many of the components are only needed so the power can be properly converted to USB-C and can be removed since I do not want that functionality?

Thanks

hi,

if you want PFC+ACF stages only, you can remove USB components.

from the schematic, you can refer the circuit before Vo.

and please do remember to modify the feedback resisters divider to get the wanted voltage.

Best Regards,

Ryan

Hi Ryan,

Thank you for getting back to me. Just for clarification, I am looking to get 5V/5A out of the design, and the way to do so is by removing the yellow boxed sections on the attached sheet. I know you indicated in the replay that I should ignore everything after Vo but the circuit is so interconnected I just wanted to make sure.

Thanks,
