How to design a reliable and safe voltage boost power supply module(1)


power module

A modular power supply is a power supply that can be directly mounted on a printed circuit board and can be used for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field programmable gate arrays (FPGAs) and other Digital or analog loads provide power. Typically, such modules are referred to as load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the obvious advantages of the modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communications fields, as well as automotive electronics, aerospace, etc.

The voltage boost 48V input power supply module is a power converter that can be directly installed on the printed circuit board. According to the conversion method, it is generally divided into AC to DC or DC to DC. With the development of technology, the power capacity tends to be modularized and miniaturized, so power modules appear. It has a high degree of integration, and integrates the main circuit of the switching 48V input power supply into the chip, which can complete broadband modulation, isolation and various maintenance functions. As more and more people have higher requirements for power modules and higher reliability requirements, today's small editor commented on how to plan high reliability power modules!
