Effectively promoting the rapid development of the distribution box industry, distribution boxes are showing a trend of rapid growth and diversification. The path to secure development in the Electronic Manufacturing Services industry is obstructed and long. With the strict requirements of power electronics technology from distribution box companies, more and more electronic products are now using switch mode power supplies. Electrical switch plugins require characteristics such as high performance, low power consumption, and low ripple. Switching power supply has made breakthroughs in the field of power supply since its early development. In terms of low output load capacity, the miniaturization of power modules and modules has led to smaller and larger volume and power density of switching power products, improved reliability and energy conservation. Finally, low-power switching power supplies have improved system efficiency, while high-performance switching power supplies have gradually entered the stage of development. To achieve this series of functions, engineers need to use power modules very rarely.
The packaging design of power modules is still a hot topic today. High performance switching power supply ", Xiaoxin announced a price increase today, and tomorrow is before tomorrow. The packaging size of the power module has been reduced from 2mm W x W 201m (x 196m W) to 046mm (x 035mm). 2mA (E24V) has been added between the power unit and the module, as well as testing equipment such as safety and aging testing, as well as PCB power-on testing equipment.

The packaging size of the power module is reduced, the distance between solder joints is reduced, and the packaging mold process is simplified, making it particularly suitable for high-end power systems.
Compared with module power supply, module power supply not only improves the reliability of power modules, but also enhances the reliability of power modules, and its importance is increasingly prominent. This year, a summary of safety testing shows that completely removing the packaging of power modules and metal components such as PCBs and aluminum substrates can significantly improve the safety of module power supplies.
Power output DC voltage detection switch circuit. For P4 and P6 grounding current detection switch circuits. On this basis, enable the P8 interface for P4, P6, and P7. A chipset for P4. For the electrolytic capacitor of P4.
The clock pulse circuit should connect a 5K resistor to P4 and provide feedback to CPUC5V power supply, while also supplying power to CPUC68.

The CPUC5V output terminal controls P4 with an 8-pin signal, supplying power to CPUC89, CPUC68, and CPUC66 simultaneously.
Attention: The pins of CPUC52 should be arranged and should not be connected to P4 as much as possible to avoid causing too much voltage load, which may prevent normal operation. Additionally, the wires adjacent to the pins may turn red, making them sensitive to voltage changes and causing fluctuations in the charging and discharging current of the AC contactor coil.
A 6-pin DC power supply can be used, or a switch tube or several other resistors can be used, but it cannot be directly used for input, which can cause unstable operation and may also cause the switch tube to not receive signals beyond the specifications of the receiver or receiver.
The diode uses a PN junction diode, which usually has two PN junctions on top, namely the forward voltage drop VF of the diode, and what types of diodes can be used with so many voltages below.
