1-Wire Bidirectional Level Converter (1.8V to 5V) Reference Setting
The designer requires 1-wire host IO to adopt open drain architecture and work at 1.8V. Most 1-wire slave devices cannot work at 1.8V. This application note introduces the reference design (RD) to realize the level conversion between 1.8V 1-wire host and 5V 1-wire slave. The reference is designed to drive a typical 1-wire slave device and realize level conversion by using max3394e level converter.introductionFPGA, microprocessor, ds2482-100 and ds2480b are common 1-wire host devices. 1-Wire/iButton The slave device is produced by Maxim, and the typical working voltage of this series of devices is 2.8V to 5.25V. In the past, the traditional 1-wire master and slave devices used 5V drain open circuit logic. Now, designers need 1-wire host IO to provide 1.8V drain open circuit logic. Most 1-wire slave devices can work safely at 5V, and most of them cannot work at 1.8V. A bidirectional level converter is needed to overcome this limitation. This reference design (RD) uses Maxim Max3394e bidirectional level converter is used to solve the problems in such applications.Level converterThe max3394e bidirectional level converter is packaged in 8-pin, 3mm x 3mm tdfn.

How to Optimize the Transformer Design in Poe Power Supply
How to Optimize the Transformer Design in Poe Power Supply
Power over Ethernet - Ethernet power supply technology refers to a way in which power supply equipment PSE (power sourcing equipment) transmits power to power receiving equipment PD (power device) through network cable. Typical applications, for example, take the PSE switch as the core and connect many PD devices through network cables, such as access point, IP phone and IP camera. PSE completes the signal and power transmission to PD.Poe power supply has the following advantages: convenient installation and expansion: network cable transmits signal and power, and there is no need to configure power interface around PD equipment remote management: one PSE device provides power for multiple PD devices, which is convenient for remote power management low cost: signal line and power line are combined into one, eliminating one power line, so network cable is not only the carrier of signal transmission, It also plays the role of power transmission, so the wiring cost is reduced good compatibility: it is not limited by the power grid standards of various countries, and the unified Poe protocol ensures that PD equipment can be compatible with any PSE worldwideFrom the perspective of circuit architecture, the PSE on the left transmits DC 44-57v to PD, and the PD on the right cooperates with step-down circuit to convert the power supply into required power. PSE and PD are connected through RJ45 interface and up to 100m twisted pair.IEEE 802.3af, IEEE 802.3at andIeee802.3bt three Ethernet power supply standards. In particular, the IEEE 802.3bt standard was released in 2019, which greatly increased the power supplied by Poe. PSE provides 90W power. After passing through 100m network cable, the received power of PD reaches 71w. This class 8 power level is mainly used in the power supply system of small base stations. Moreover, 802.3bt standard is downward compatible with 802.3af and 802.3at standards; When the 802.3bt PD is connected to the low-power 802.3af and 802.3at PSE, it will work in the low-power state, that is, "degraded".In this process, the lower power PD is connected to the higher power PSE, and the equipment is not damaged. The following handshake process is mainly experienced when the PSE supplies power to the PD:Pictures from the InternetThe picture comes from the network, and the chart comes from the inside of shunluoIn the circuit architecture of PD equipment, three parameters are mainly concerned: size, efficiency and EMC. Then how to connect the requirements of PD equipment and the design requirements of transformer.//3.1 optimized size key points of design 1: reduce the size of the transformer with high frequency. In a circuit board, it can be seen that the larger the volume is the transformer, so reducing the size of the transformer can save the size of the board. High frequency can reduce the size of transformer and power transmission of transformer, so the frequency from 200 kHz to 300 kHz to 500 kHz can reduce the volume of transformer. Design point 2: CCM working mode reduces device size design point 3: primary side feedback reduces sizePictures from the Internet3.2 improving efficiencyEMC measures the interference of noise source on sensitive equipment, including conduction and radiation composition. On the one hand, reduce the interference source, on the other hand, optimize the coupling path.In order to reduce EMI, first confirm the noise source in the circuit. The noise source is divided into conduction noise source and radiation noise source. The conducted noise source is generally low-frequency noise within 30MHz, which is generated by the change of electric field; The conduction noise source is mainly the switching action of the power tube, which will lead to the sudden change of MOS source level voltage, which will lead to the transformer transmitting the sudden change of voltage to the secondary side. Increasing the driving resistance of MOS can reduce the switching speed, but the driving loss will increase; Or increase the absorption circuit to reduce the high-frequency oscillation. Stray parameters of transformer have a great impact on EMI. For example, transformer CP (primary winding electric field) affects voltage spike and current ripple.The radiated noise source is the noise above 30m, which is the interference of spatial magnetic field and consists of high-frequency current loop. High frequency loop refers to the primary side loop and secondary side loop of transformer. During PCB layout, the loop path should be reduced to reduce noise, or small capacitance in parallel should be added.3.3 shunluo electronic transformerShunluo electronics has a strong transformer design team. In the transformer design of Poe power supply, it comprehensively optimizes the transformer design from the perspective of size, efficiency and EMC to meet the customized needs of customers. Shunluo electronics has a fully automatic transformer production line to ensure the reliability and consistency of products and short delivery cycle. You are welcome to place an order.Editing: JQ

Analysis of Common Causes of Notebook Screen Darkness
Analysis of Common Causes of Notebook Screen Darkness
If you find that the notebook's display screen (TFT) is very dark when you turn it on, the contrast and dark notebook screen is still very dark and can't be seen clearly. That's the screen darkHow does the screen darken? There are four common situations:The first is the problem of the lamp tube. The aging or short circuit of the lamp tube will darken the display screen. If the lamp tube has a problem, it can only be replaced by a professional maintenance company. The aging and short circuit of the lamp tube rarely occur. The aging is generally due to long-term use or collision during use (the service life of the lamp tube in normal use can reach about 3 5 years). The short circuit is caused by the metal in the screen shell, If the screen shell is broken, use it carefully to prevent short circuit.The second is that the main board has no voltage for the high-voltage board. Problems, aging or short circuit of the main board will occur. Most of them can be repaired. It is not necessary to replace the main board.The third is the aging or burning of the high-voltage board, or the loosening and burning of the power connection line of the high-voltage board. The screen darkness caused by the high-voltage board is more common, because the high-voltage board works at high temperature for a long time, the chip will be easier to age or burn outThe fourth is the broken screen line, which is often the cause of screen darkness, because NB is folding. Opening and closing the screen too hard will wear the screen line, and frequent use will easily cause the broken screen line.Generally, problems with the graphics card will not cause the screen to be dark. Most of them are flower screen or no display. In addition to the replacement of the lamp tube, the replacement of a non original high-voltage plate may cause the dimmable brightness of the LCD screen to fail (the impact depends on the individual). Generally, the high-voltage plate can be repaired.Conclusion: generally, it is not recommended to disassemble and repair by yourself.
