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 application provides a power conditioning device comprising a first resistor circuit, a second resistor circuit and a control unit, wherein a DC voltage input port is connected to a grounding linethrough the serially connected first resistor circuit and the second resistor circuit; the control unit is configured to control the DC voltage input port to supply power to a digital circuit, or thefirst port between the first resistor circuit and the second resistor circuit supplies power to the digital circuit. The above manner can realize voltage regulation, provide DC voltage suitable for the circuits for different digital circuits to supply power to the digital circuits, and at the same time, reduce the manufacturing cost.

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...
