Explain complex switching power supply knowledge in a simple and easy-to-understand manner, use simulation methods to assist teaching, and teach you step by step how to develop practical switching power supplies.
[b]Specifically, it is to transmit the environmental detection data of temperature, humidity and PM2.5 from the detection system to the control terminal. I don’t understand the personal instructions.
The positive and negative 10V of the computer serial port can drive the LCD, but the positive and negative 7V signal I output through MAX232 using 51 cannot drive the LCD. What's the situation? Can so
In the DCDC power supply test, the load transient test is a very important part. The load transient test can be used to quickly evaluate the stability and speed of the tested power supply. When select
