BL8033 step-down module (5V3A) verification board

Overview

This project is used to verify the solution verification board design of Lichuang Mall DC-DC power IC BL8033CB6TR .
This project is a sample project for the Solicitation Order for Lichuang EDA open source hardware platform solution verification module .
- -
This design is a 5V3A step-down power module based on BL8033CB6TR .
BL8033CB6TR is a 4.2V~16V input, 3A, 500KHz, synchronous buck converter that does not require Schottky diodes. The circuit is very simple and reliable, so this solution uses the DC-DC power IC BL8033CB6TR from Lichuang Mall .
The input and output are led out through pin headers.

Shouldn't just leave the pins? It's too difficult for me.

The test works perfectly, and I will test the power performance later (not yet, and I don’t have the equipment) Demo video of station B

I used a multimeter to measure the power of the small motor connected and it was 5vx1.2A=6W. The input was 12V2A on the router.

Question D
When doing filter filtering, I found that the low-level filter is generally used to 10th order, and the high-level filter is generally used to 6th order. I feel that there will be big problems: Sad:
Anyone who has used SOFTICE please come in and take a look, and ask for help online.
