The name of wireless router can be separated out of two keywords: wireless and routing. Understand the technical principle behind these two words, you understand the wireless router.

Wireless is also what we often call Wi-Fi. Wireless routers can convert home broadband from wired to wireless signals, and all devices can happily surf the Internet as long as they connect to their own Wi-Fi. In addition, these devices also form a wireless local area network, where local data is exchanged at high speed and is not limited by the bandwidth of home broadband.
For example, many people have smart speakers in their homes that can be used to control various smart appliances. When you say small X small X, turn on the TV, the speaker actually finds the TV through the LAN and sends instructions, and does not need to connect to the Internet; And if you let it broadcast news, you have to get data through the Internet.
The Local Area Network we talked about earlier, also known as the Intranet, is represented by the Local Area Network (LAN) on the router, so the Wi-Fi signal is also called WLAN(Wireless LAN); The Internet we want to access, also known as the extranet, is represented on the router by the WAN(Wide Area Network).
On the Intranet, the IP address of each device is different, which is called a private address. All devices on the Internet share the same public address, which is assigned by broadband operators such as China Telecom Unicom.
The router is the bridge between the Intranet and the external network. The above mentioned IP address translation, packet forwarding, is the router routing function.
In other words, the router is the hub of the home network, and the data of all the devices must be forwarded through it to access each other or reach the external network, which means that one husband is the key and ten thousand men are not open, so the comprehensive router is also called "home gateway".
What are the classifications of power management chips?
In today's world, people are increasingly dependent on electronic devices, and this reliance continues to grow. As technology evolves rapidly, there is a rising expectation for more advanced power supply solutions. This article provides an overview of the main categories of power management technologies.
Power management semiconductors play a crucial role in managing electrical energy efficiently. They consist of two main components: power management integrated circuits (PMICs) and discrete power semiconductor devices. PMICs are essential in controlling and regulating power within various systems, while discrete devices like diodes, thyristors, and transistors are used for more specific applications.
PMICs can be broadly categorized into voltage regulators and interface circuits. Voltage regulators include linear low-dropout regulators (LDOs), switching regulators, and other specialized types. Interface circuits handle tasks such as driving motors, managing high-voltage displays, and controlling MOSFETs. These components are vital in ensuring stable and efficient power delivery across different electronic systems.
On the other hand, discrete power semiconductor devices are traditional components that have been widely used in power electronics. They include rectifiers, thyristors, bipolar transistors, and more modern devices like MOSFETs and IGBTs. These components are often used when higher power handling or greater flexibility is required.
The development of PMICs has led to a shift in terminology, with power semiconductors now commonly referred to as power management semiconductors. This change reflects the growing importance of integrated circuits in power management solutions. Today, many ICs are specifically designed for power-related functions, making power management a central focus in modern electronics.
There are eight main types of power management ICs:
1. AC/DC modulation ICs – Used for converting alternating current to direct current.
2. DC/DC modulation ICs – Include boost, buck, and charge pump regulators.
3. Power Factor Correction (PFC) pre-modulation ICs – Improve input power quality.
4. PWM/PFM control ICs – Control external switches using pulse modulation techniques.
5. Linear modulation ICs – Such as LDOs, which provide stable voltage regulation.
6. Battery charging and management ICs – Handle battery charging, protection, and monitoring.
7. Hot-swap control ICs – Enable safe insertion and removal of components.
8. MOSFET/IGBT switching ICs – Used for high-power switching applications.
Among these, voltage regulation ICs are the fastest-growing segment. Each type of power management IC is tailored for specific applications, allowing for a wide range of solutions in different industries.
The future of power management is moving toward higher efficiency, lower power consumption, and smarter systems. Engineers are working to improve energy conversion efficiency while reducing the physical size of components. In AC/DC conversion, for example, low on-state resistance is becoming essential for more efficient power supplies in computers and telecommunications.
Additionally, standby power consumption has significantly decreased, with many devices now consuming less than 1W when idle. The power efficiency of modern systems can exceed 90%, but further improvements require advancements in manufacturing processes and low-power circuit design.
Overall, power management is a dynamic field that continues to evolve with technological progress, ensuring that electronic devices operate more efficiently and reliably than ever before.
