Hello, When there is no load, the PWM HO and LO outputs will appear PWM periodically and briefly, accompanied by a whistle of the inductor. At this time, the input voltage will also have a downward peak value, and the output voltage will be unstable. When loaded, the input voltage is no longer a con...

The TL431 is an integrated precision voltage regulator. The( TL431AIDBZR,215 )can provide accurate reference voltage due to its high control voltage precision and small temperature coefficient. This gadget is also used in switching circuits like battery vehicle chargers, induction cooker circuits, a...

Hello! This is small talk about NE555 and LM555. In fact, many people ask what difference between NE555 and LM555 , or are they interchangeable? After reading an article(https://www.utmel.com/components/lm555-vs-ne555-what-difference-is-between-lm555-and-ne555?id=1111) which talks about their differ...

Hello！ I would like to know how I want to know how far CAN communication composed of MCP2515 + TJA1050 can be transmitted? I checked a lot of information, but I couldn't find a specific example to illustrate under what circumstances the TJA1050 can reach a transmission distance of several kilometres...

I want to ask if the following circuit is feasible. The load current is about 100mA. I have read the LM1117 manual (https://www.utmel.com/components/lm1117-voltage-regulator-pinout-equivalents-datasheets?id=144) and seen that the input and output terminals are connected with 10uF tantalum capacitors...
