Abstract

The invention discloses an integrated DC / DC (Direct Current) power source front-end control system. The integrated DC / DC power source front-end control system at least comprises an integrated DC / DC power source front-end controller, wherein one integrated DC / DC power source front-end controller works in a main working mode, and other integrated DC / DC power source front-end controllers work in a slave working mode; the integrated DC / DC power source front-end controller working in the main working mode outputs a clock signal to the integrated DC / DC power source front-end controllers working in the slave working mode. The power consumption can be reduced particularly when multiple groups of integrated DC / DC power source controllers compose an integrated power source front-end control system, and resources are saved. Meanwhile, a DC / DC conversion function with different voltage demands is realized through connecting one or more transformers.

Description

technical field [0001] The invention relates to the field of power supply of a power supply module, in particular to a front-end control system powered by a DC / DC power supply. Background technique [0002] The power supply is an essential part of all electronic equipment and is the "power source" of the equipment. The DC regulated power supply is the most basic part of the power supply, and its performance directly affects the reliability of electronic equipment. With the continuous development of semiconductor technology and the different needs of various electronic products, a wide variety of power modules have emerged. [0003] There are many power module products on the market at present, among which the best ones and the most used ones belong to TI's products. TI's DCP10505 is a high-efficiency 5V input DC / DC conversion power chip with output short-circuit protection and overheating shutdown functions. Its circuit block diagram is as figure 1 As shown, but the sync...
