Main Component Introduction Briefly; please refer to the introductory LED blinking LED Breathing Light Introduction Digital signals are represented by 0 and 1, which indicate non-continuous changes in voltage levels, while analog signals represent information through continuously varying physical quantities, with signals changing continuously over time. Most of the signals we encounter in our lives … Read more
A design is needed for an isolated circuit that outputs a variable voltage of 0~12V, with the isolated side powered by 12V. There are no specific speed requirements for the output voltage. The accuracy is not particularly critical, as it just needs to stabilize once set. The design uses an optocoupler driven by the PWM … Read more

We currently have standard techniques for generating negative output voltages and methods for dynamically adjusting output voltage. In this article, I will introduce the missing link between these two technologies—a level-shifting circuit that combines them. Applications requiring negative output voltage include: testing and measurement, aerospace and defense, automotive, and medical. A common method to create … Read more
