Module power supply is a power supply that can be directly mounted on printed circuit boards, providing power for specialized integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field programmable gate arrays (FPGAs), and other digital or analog loads. Generally speaking, these types of modules are referred to as load (POL) power supply systems or point of use power supply systems (PUPS). Due to the obvious advantages of modular structure, modular power supplies are widely used in communication fields such as switching devices, access devices, mobile communication, microwave communication, optical transmission, routers, and automotive electronics, aerospace, etc.The selection of module power supply should consider the following points:1. Consider the output power of the product:1-60W, it is generally recommended that the actual power used is 30-80% of the rated power of the module power supply (the specific proportion is also related to other fac...

Generally speaking, the application architecture of fast charging adapters mainly includes three modules: AC-DC conversion module, power control module, and fast charging protocol module. Among them, the AC-DC conversion module is responsible for converting 220V AC power to DC power, the power control module is mainly used to adjust the DC voltage to the voltage required by the phone, and the fast charging protocol module is responsible for shaking hands with the phone to communicate, collecting voltage, current, and various information requested by the phone.CPW3301 not only integrates power control module and fast charging protocol module, shouldering the core task of the entire fast charging process, but also specifically solves a series of pain points of current power adapters in the market.Firstly, the power management module of CPW3301 has high integration and rich functionality. This chip integrates two of the three main modules of the fast charging adapter: the power control...

Electric bicycles are green, clean, convenient, and low-cost, making them a popular choice for many residents. With the widespread application of electric bicycles, safety accidents caused by issues such as wiring and charging are becoming more common. The capacity, safety factor, health condition, and endurance of electric bicycle batteries have gradually become a focus of attention.On March 26, 2019, the Ministry of Industry and Information Technology announced that the new mandatory national standard for electric bicycles, "Safety Technical Specifications for Electric Bicycles," was officially implemented on April 15, 2019. Although the country has not yet decided to phase out lead-sealed batteries, the trend of replacing lithium-ion batteries with lead-sealed batteries and intelligentization for electric bicycles has become inevitable. Compared to the widely used lead-sealed batteries in this field, lithium batteries have advantages such as high operating voltage, small size, hi...
