Fast charging source module based on XXDCDC-SW2303

 
Overview

Use XXDCDC’s fast charging module.

The board terminal limits the input to a maximum of 28V.

Output default 5.2V

 

*Remove input TVS maximum input 35V.*

*Replacing the input components can withstand a maximum input voltage of 60V.*

 

Human flesh efficiency table. Without calculating the insurance voltage drop, the actual voltage is about 0.03% higher than the table, which is not a big difference.

This table shows the chip-side efficiency. The board-side efficiency will be about 1% lower (factors such as wiring resistance + sampling + USB contact resistance).
