Description
Power module LYA210A is a power supply that can be mounted directly on the printed circuit board. LYA210A is characterized by specific integrated circuits (ASics), digital signal processors (DSP), microprocessors, memory, field programmable gate array (FPGA) and other digital or analog loads. Generally, such modules are called load (POL) power supply systems or point-of-use power supply systems (PUPS). LYA210A because of the advantages of modular structure, so the module power supply is widely used in switching equipment, access equipment, mobile communication, microwave communication and optical transmission, router and other communication fields and automotive electronics, aerospace, etc.
Function description:
Switching power supply in the input anti-interference performance, because of its own circuit structure characteristics (multistage series), the general input interference such as surge voltage is difficult to pass, in the output voltage stability this technical index compared with linear power supply has a greater advantage, its output voltage stability can reach (0.5 ~ 1) %. Switching power module as a power electronic integrated device, in the selection should pay attention to the following points:
Because the switching power supply work efficiency is high, generally can reach more than 80%, so in its output current selection, should accurately measure or calculate the maximum absorption current of electrical equipment, so that the selected switching power supply has a high performance-price ratio, usually output calculation formula is:
Is=KIf
Where: Is – rated output current of switching power supply;
If – the maximum absorbed current of the electrical equipment;
K – margin coefficient, generally 1.5 ~ 1.8;
