Why should the vehicle voltage booster/buck power supply module be tested for aging(3)

The key methods of DCDC converters supply embrittlement include load embrittlement at normal warm temperature and high and low temperature test with high temperature plug in. The common method is high temperature embrittlement. According to the high temperature embrittlement, the shortcomings or poor quality of commodity components can be exposed, thereby improving the reliability and credibility of the commodity.

The high temperature embrittlement of the vehicle voltage booster/buck power supply module refers to the simulation of the high temperature application natural environment of commodities. The high and low temperature test time is usually specified as 12-48 hours. There are two high temperature embrittlement steps, which are set in a high temperature natural environment to embrittle when plugged in. This is an impact DCDC converters supply with more extreme natural environment standards under high temperature natural environment.

Function of high and low temperature test of vehicle voltage booster/buck power supply 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.

1. When the power module is embrittled, the monitor on the computer can be used to see the statistical data of the power supply under the working attitude, which reflects the application of the power supply.
