Description

Technical field [0001] The invention relates to a DC / DC power supply module, in particular to a digital DC / DC power supply module with multi-mode and multi-loop control. Background technique [0002] With the development of science and technology, DC / DC power modules are widely used in remote and data communications, computers, office automation equipment, industrial instrumentation, military, aerospace and other fields, involving all walks of life in the national economy. DC / DC power modules have become an important part of many electronic devices, and their quality directly affects the performance of electronic devices. In addition to conventional electrical performance indicators, small size, high efficiency, low voltage and large current output, and high reliability are also required. This application demand trend poses a severe challenge to the design of DC / DC power modules. [0003] Most common DC / DC power modules in China are mainly based on analog circuits and a single con...
