The power supply module can be directly mounted on the printed circuit board. Its characteristics are that it can supply power for ASIC, digital signal processor (DSP), microprocessor, memory, field programmable gate array (FPGA) and other digital or analog loads.
Generally speaking, such modules are called load point (POL) power supply system or point-of-use power supply system (PUPS).
Because of the advantages of modular structure, modular power supply is widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, router and other communication fields, automotive electronics, aerospace and so on.
