What kind of 主词六替换 will be higher(2)
The secondary power DC/DC converter of the communication power supply has been commercialized. The module adopts high-frequency PWM technology, the switching frequency is about 500kHz, and the power density is 5W~20W/in3. With the development of large-scale integrated circuits, the module power supply is required to be miniaturized, so it is necessary to continuously increase the switching frequency and adopt new circuit topologies. The power density of the module power supply has been greatly improved.
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 48V input power supply is the IC, which is like the brain of the 48V input power supply. The quality of the IC can directly affect the various working parameters of the 48V input power supply.
