A power module is a power supply that can be directly mounted on a printed circuit board. Its characteristic is that it can provide 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, this type of module is called a Point of Load (POL) power supply system or a Point of Use High Power Power Supply System (PUPS). Due to the many 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.
Especially in recent years, due to the rapid development of data business and the continuous promotion of distributed power supply systems, the growth rate of power modules has exceeded that of primary power supply. With the widespread use of semiconductor technology, packaging technology, and high-frequency soft switching, the power density of modular power supplies is increasing, the conversion efficiency is becoming higher, and applications are becoming simpler.
The power module uses an AC/DC converter controlled by an integrated chip with excellent characteristics, which has excellent off screen anti-interference characteristics and electromagnetic compatibility. The pin uses 5PIN, 24PIN and other dual in-line plug, and is packaged with metal copper and high flame retardant plastic shell. It can operate without any external peripheral components.
