The 12v to wall plug module is a power converter, which can be directly installed on the printed circuit board. According to the different transformation methods, it is usually divided into AC to DC or DC to DC. With the development of technology, the power supply capacity tends to be modular and miniaturized, and the power supply module emerges as the times require. It has a high degree of integration, and integrates the main circuit of switching power supply into the chip to realize the functions of broadband modulation, isolation and various protection. With the increasing demand for power module, the demand for reliability is also higher and higher.
So, what elements should be included in the design of high reliability power supply module?
1、 Design of surge protection circuit
How to design surge protection circuit according to different application situation can adjust the position of inductor / TV tube, so that the system can apply the circuit better and correctly, so as to improve the electromagnetic compatibility performance. Pay attention to the design of two-stage surge protection circuit. If it is used improperly, it will be counterproductive.
2、 Reduce the number of designs
To control the components to the specified value correctly and reduce the number of components can delay the degradation of components, improve the reliability of components and power supply.
