Introduction of 12v2A high current synchronous rectification chip U7718
If the synchronous rectification MOSFET gets hot, we must first analyze the signal controlling the MOSFET, mainly to see whether the signal is reasonable, and whether it is hot in DCM or CCM? Similarl
Analysis of the structure and working principle of inductors
Inductor (also known as Choke) is a component that can convert electrical energy into magnetic energy and store it.Inductors are similar in construction to transformers, but with only one winding. Ind
Things That Have to Be Said About DIP Devices
Learn about DIPsDIP is a plug-in. The chip with this packaging method has two rows of pins, which can be directly soldered to a chip socket with a DIP structure or soldered to a soldering position wit
How to view the voltage deviation of self-healing parallel capacitors?
Voltage is one of the most important indicators in the field of electric energy quality. Once there is voltage deviation, it will not only have a negative impact on related electrical equipment, but a
Why use a bipolar transistor to drive a power LED?
High power LED strings (such as those used in car headlights) require constant current, that is, regardless of the fluctuation of the ambient temperature and input voltage, the current remains stable.
What is a high frequency transistor?
A high-frequency transistor is a transistor used for high-frequency signal amplification and processing. Compared with ordinary transistors, high-frequency transistors have higher operating frequency
What should I do if the inrush current occurs during the operation of the compensation capacitor?
Using compensation capacitors for reactive power compensation is one of the effective measures to effectively improve power quality, but in actual operation, various abnormal phenomena may occur due t
The symptoms of a broken 220V motor capacitor
The symptoms of a broken 220V motor capacitor may include:Difficulty or failure to start: Capacitors are one of the key components in starting a motor. If the capacitor is damaged, the motor may have
What is the difference between dry-type transformer Dyn11 and Yyn0?
The main differences between the dry-type distribution transformer Dyn11 connection transformer and Yyn0 are: phase electromotive force waveform, low loss, heat generation, ability to suppress harmoni
Why is it easy for running compensation capacitors to have temporary overvoltage?
Only by understanding the problems that may be encountered during the operation of reactive compensation capacitors can we better deal with various situations during the operation of capacitors.Now th
Interpretation of the ADA4940-2 Ultra Low Power Low Distortion ADC Driver
The ADA4940-1/ADA4940-2 are low noise, low distortion, ultra-low power differential amplifiers, making them ideal for driving low power, high resolution, high-performance SAR and Σ-Δ type analog-to-di
What is the CS8390E IC used for? How can I make use of it?
The CS8390E is a highly integrated, low-power, single-chip Ethernet controller designed for embedded systems. It is designed to provide a complete Ethernet solution for embedded systems, including net
Why do all electronic devices work on DC?
The use of direct current (DC) in electronic devices is a result of the fact that DC power is more reliable and efficient than alternating current (AC). DC power is also easier to control and regulate
How do I test a power transistor?
Testing a power transistor is an important part of ensuring that your electronic device is functioning properly. A power transistor is an electronic component that is used to amplify or switch electri
Detailed explanation of the method for judging the positive and negative poles of SMD light-emitting diodes
SMD diodes are also called crystal diodes, or diodes for short. In addition, there are early vacuum electronic diodes; it is an electronic device that conducts current in one direction. There is a PN
