Abstract

The invention relates to a power module supporting wide voltage inputting. The power module comprises an input interface, an input protection module and an output adjustment module, wherein the input interface is electrically connected with the input protection module, the input protection module comprises an input reverse-connection protection module and an input surge protection module, the output adjustment module is connected with the input protection module and comprises a switching power supply module. Output voltage is adjustable, input voltage has the reverse-connection preventing protection design, the input / output voltage has the functions of overvoltage protection, overcurrent protection and undervoltage protection, and can be matched with a system to achieve the functions of starting and powering off in a delayed manner.

Description

technical field [0001] The invention relates to the field of power supply design, in particular to a power supply module supporting wide voltage input. Background technique [0002] Almost all current electronic devices are driven by power supplies, but different devices have different requirements on the performance parameters of power supplies. Today, the scope of motherboard industry applications is getting wider and wider, for example, industrial control, automotive electronics, billboards and other fields. Such industrial applications basically use DC power adapters as power supplies. At present, the power adapters used in the traditional PC industry are fixed input voltage adapters (19V and 12VDC input), so many products in the market need to match these standards. However, with the diversified and refined development of the industry, in order to meet energy consumption standards and meet the needs of specific industries, the electronics industry requires motherboard...
