What kind of LED advertising screen power supply will be higher(2)
reasonable core structure and compact structure.
At the same time, in order to reduce the size of the module switching power supply, the switching frequency of the module switching power supply should be increased as much as possible. If it is to be increased to about 500kHz or higher, the loss of the ordinary magnetic core material is very large, and the magnetic core is easily overheated and magnetically saturated, and even It cannot work normally, so the high-frequency magnetic core material with excellent magnetic properties must be selected in the module switching power supply.
The quality of the resolution of the circuit schematic is usually done from a professional perspective. This power module can be divided into two kinds of bare board and packaged, according to an intuitive way of bare board, such as electronic components layout is reasonable and orderly, generous, orderly, and the net pad is lit upright. Also, stationary modules will not be able to see what's going on inside, but it's much better not to be exposed due to safety and performance levels. The soldering process can include both wave soldering and manual soldering, and the quality of the mechanized production process of wave soldering is superior to that of manual soldering.
Two: the components of the chip
The core problem of the Marine boost voltage power supply is the IC, which is like the brain of the Marine boost voltage power supply. The quality of the IC can directly affect the various working parameters of the Marine boost voltage power supply.
