LDSYN-101 3BHE005555R0101 Power module

Product details:

The role of the power module is the conversion of voltage, it can be AC or direct current into the AC or direct

current you need. Such as: the mains 220V alternating current (AC) into 5V direct current (DC), because the AC

220V electricity is high voltage, and electronic products are low voltage power supply, this requires a conversion device,

the AC 220V voltage into low voltage. For example, in the motor vehicle sometimes need to be converted to 220V

alternating current to use, so this will become a low voltage to high voltage, because the voltage of the motor vehicle is generally relatively low.

In short, it is similar to the mobile phone charger, your mobile phone is out of power, you need to plug in or charge it to

work normally, but you can not directly use 220V, because then the phone will burn, so you need a special conversion device to convert the voltage required by the mobile phone.

1. Circuit design principle and process

The distinction between good and bad circuit principles is usually only from a professional point of view. At the present

stage, the power module can be roughly divided into bare board and potting. The bare board can be based on the

intuitive way, such as the layout of electronic components is reasonable and orderly, generous and orderly, and the

solder joint is bright, clean and straight. And potting module, can not see the internal situation, but because not exposed,

in the level of security and performance indicators much better. The welding process can include manual welding and

wave soldering process. The quality of mechanized wave soldering process is better than that of manual welding.

2. Components of the chip

The core of the power supply is IC, which is like the brain of the power supply. The quality of IC directly affects the parameters of the power supply.

3. Transformer components

The transformer determines the power and temperature resistance of the power supply. The transformer is responsible for AC – DC, energy overload will saturate the machine
