When LM5117 is used as a step-down DC voltage regulator circuit and connected to an LCD screen, the efficiency is pulled down to less than 85%, and the temperature drift caused by the load resistor af
The advantage of electronic tag conductive adhesive in reducing costs RFID tags, as a kind of smart tags, are being valued by more and more users and label manufacturers. However, this type of label i
This article mainly introduces the relevant information of electric vehicle batteries, and focuses on the charging problem of electric vehicle batteries. Electric vehicle batteries are the power sourc
The simplest RC reset. Resistor 10K, capacitor 10uF. This board works perfectly fine with AT89S51. But when it is replaced with SST89C58, the power-on reset is extremely unreliable. It never resets su
A multi-resonant DC/DC converter that is very suitable for working at ultra-high frequency is analyzed. All the switch tubes of the converter work in the ZVS state, and all the rectifier diodes work i
