The power supply module is a power supply that can be directly mounted on a printed circuit board, and is characterized by being a dedicated integrated circuit (ASIC), Digital signal processor (DSP)
, Microprocessor, memory, field programmable gate array (FPGA)And other digital or analog loads to provide power. In general, such modules are called load points (POL)
Power supply system or point-of-use high-power power supply system (PUPS).
As the modular structure has many advantages, the module power supply is widely used in the communication fields such as switching equipment, access equipment, mobile communication, microwave communication, optical transmission, router, automotive electronics, aerospace, etc.
Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the growth rate of power supply modules has exceeded that of primary power supply.
With the extensive use of semiconductor technology, packaging technology and high-frequency soft switches, the power density of the module power supply is getting larger and larger, the conversion efficiency is getting higher and higher, and the application is becoming more and more simple.
The power supply module uses an AC/DC converter controlled by an integrated chip with excellent characteristics, has excellent anti-interference characteristics and electromagnetic compatibility, and uses double in-line insertion such as 5PIN and 24PIN for the pin position, metal copper and high flame retardant plastic shell package can operate without any external peripheral components.
