Problem description:
1. The designed buzzer drive circuit is shown below. The resistor in the figure was later changed to 470Ω, but the problem was still not solved;
2. The buzzer is an active buzzer;
I recently used the LM2596 chip to draw a power module, 20V DC input, connected a 25V100uF tantalum filter capacitor at the input end, connected to the load, the total current of the circuit was about

For an integrated development environment, code editing is not only the most basic and necessary function, but also an important part that directly affects the user's development experience. The main
Millimeter wave filter technology is an important part of achieving mainstream 5G wireless communications, but there are many difficulties in physical size, manufacturing tolerance and temperature sta
