sct2650 power board

Overview

A step-down power supply board based on sct2650, with an output voltage of 5V, a maximum output current of 5A, and an indicator light. Tested and effective.
More via holes were drilled, and the power loop was covered with copper as much as possible to reduce the area, and the feedback resistor was close to the chip.

Referring to the technical manual, the maximum output current is calculated based on the

0.8V feedback voltage

R3 of the FB pin of the 5A chip. For details of the undervoltage lockout voltage and enable voltage of the chip,

please also refer to the sct2650 technical manual.

The soldered board has been tested. The input is 24V and the output is The size of the 4.88V

board can be used for free. I chose blue solder mask, which has a good texture.
The materials can be purchased more easily at Lichuang Mall. It is recommended that you try to choose the same warehouse for delivery to save shipping costs.
