1. In order to test the students' PCB practical operation, we have modified the package pad size of LM4766. If you want to use this open source project, please check the package of LM4766 and replace it with the chip package provided by Lichuang.
2. Since the chip has high power, please dissipate the heat of the board chip and increase the trace width according to the needs to avoid excessive current for a long time.
3. This project is a PCB design competition entry. If there are any deficiencies in the design of this project, you are welcome to make changes according to your needs.
4.Typical applications:
5. Bridge application:
6. Power supply: It is recommended to use 18V AC input. In the actual measured version, the heat dissipation is good, and the single channel can reach about 35W when the wires are tinned.
7. A handmade board in the laboratory
