I have made several similar circuit boards before and they are all good. There is no problem with the circuit schematic. It is a standard circuit designed with uc3842, with 4 output voltages, one of w...
As the title says, I searched the National Intellectual Property Office yesterday for a whole day and didn't see any patent number for PSP. Why don't companies develop an intelligent system that can b...
At present, it is generally recommended to use synchronous timing circuits for large designs. Synchronous timing circuits are based on clock trigger edge design, which puts forward higher requirements...
I found several troublesome places on the 51 board: First, it is better to use MAX3232 instead of MAX232, so that the 3V microcontroller can be used.Second, the CPU should also choose a 3V microcontro...
The DMA settings of the example dsk_app (examples\dsk5510\bsl\dsk_app) included with C5510DSK, resulted in two problems, which will generate noise when the program is running. First, let's briefly int...
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
The Mobile Industry Processor Interface (MIPI) Alliance is an organization responsible for promoting the standardization of software and hardware in mobile devices. It has released the D-PHY specif...[Details]
In public places such as schools, government agencies, factories and mines, as well as public corridors in residential areas, the phenomenon of long-burning lights is very common, which causes a h...[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
As cellular phones become more advanced, the power consumption of the system during operation and the power consumption during standby are also increasing. Therefore, the power management design of...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
Smart lighting control systems provide high controllability for various buildings and further enhance the level of green energy. They are the core products of energy conservation and digital techn...[Details]
With the continuous consumption of earth's energy and the scarcity of resources, the harm of greenhouse effect to human beings, and the serious pollution of the atmosphere to the earth, the intern...[Details]
The traditional display screen using 51 single-chip microcomputer to control LED dot matrix has relatively simple functions. If it is to achieve diversified functions, it often takes a lot of time ...[Details]
FPGAs are used in 81% of electronic systems, including many commercial and defense products, and most FPGAs use BGA packaging. The BGA packaging is characterized by small solder balls and small sol...[Details]
Since the late 1990s, with the demand for higher system efficiency and lower power consumption, the technological update of telecommunications and data communication equipment has promoted the deve...[Details]
