Problems solved by technology

Due to the limitation of the PMU's own resources, only a limited number of voltage-adjustable power ports can be provided, while the voltage output of other ports is fixed and cannot be adjusted
An adjustable voltage low dropout regulator (LDO) can be used to realize power supplies with different voltage values, but the cost of the LDO is relatively high

Abstract

The present application provides a power regulating device, which is characterized in that it includes: a first resistance circuit, a second resistance circuit, and a control unit; the DC voltage input port is connected through the first resistance circuit and the second resistance circuit in series to the ground wire; the control unit is used to control the DC voltage input port to supply power to the digital circuit, or the first port between the first resistance circuit and the second resistance circuit to supply power to the digital circuit. Through the above-mentioned method, voltage adjustment can be realized, different digital circuits can be provided with DC voltages suitable for the circuits, and the digital circuits can be powered, and at the same time, the manufacturing cost can be reduced.

Description

technical field [0001] The present application relates to the technical field of power supplies, and in particular to a power regulation device and electronic equipment. Background technique [0002] Currently, many electronic devices use a power management unit (PMU) to manage power. In electronic equipment, the applicable voltages of electronic components provided by different manufacturers may be different. In order to reduce the limitation of product assembly, mobile phones need to be compatible with electronic components of different applicable voltages. Due to the limitation of the PMU's own resources, only a limited number of voltage-adjustable power ports can be provided, while the voltage output of other ports is fixed and cannot be adjusted. A low dropout regulator (LDO) with adjustable voltage can be used to realize power supplies with different voltage values, but the cost of the LDO is relatively high. Contents of the invention [0003] The present applicat...
