Embodiment Construction

[0016] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] A power management system such as figure 1 , figure 2 As shown, it includes an ultra-low power regulator module that provides power to the load module in standby mode, a high-power regulator module that provides high-performance power to the load module in active mode, and: used to act as the load When the module enters the standby mode, an enabling signal is received to turn off the high power consumption regulator module, and turn on the ultra-low power consumption regulator module; when the load module enters the working mode from the standby mode, After the high power consumption regulator module is turned on, the bilateral selection switch module of the ultra-low power consumption regulator modu...

Abstract

The invention discloses a power management system, and relates to the technical field of integrated circuits. The power supply management system comprises an ultra-low power consumption voltage stabilizer module for supplying power to a load module in a standby mode, a high power consumption voltage stabilizer module for supplying power to the load module in a working mode, and a controller, the switching module is used for receiving an enable signal to switch off the high-power-consumption voltage stabilizer module and switch on the ultra-low-power-consumption voltage stabilizer module when the load module enters a standby mode; and when the load module enters the working mode from the standby mode, the high-power-consumption voltage stabilizer module is switched on, and then the bilateral selection switch module of the ultra-low-power-consumption voltage stabilizer module is switched off. According to the power management system, the voltage stabilizer modules with different power consumption and different performances are selected through the bilateral selector switch module to supply power to the load module, and the power consumption and performance requirements of the load module in different modes are met.

Description

technical field [0001] The invention relates to integrated circuit technology, in particular to a power management system. Background technique [0002] At present, some electronic devices on the market still need to be on standby or run to perform specific functions when they are not working. The power management system is an indispensable and important part of various electronic devices. However, the electronic equipment in the prior art generally has a high standby power, or when switching from the standby state to the working state, the response time is long, which affects the normal operation of the electronic equipment, increases the mode switching time and the energy loss when switching modes. Contents of the invention [0003] The main purpose of the present invention is to provide a power management system aimed at reducing mode switching time and energy consumption. [0004] In order to achieve the above purpose, the present invention provides a power management...
