Title:
METHOD FOR ADJUSTING ENERGY EFFICIENCY OF POWER SUPPLY OF TERMINAL AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/120214
Kind Code:
A1
Abstract:
A method for adjusting the energy efficiency of a power supply of a terminal and the terminal, related to the field of circuits, allowing, in a scenario in which an LDO is connected after a DC-DC voltage converter (1), quick configuration of an output voltage of the DC-DC voltage converter when a change occurs in the state of the LDO, thus allowing a voltage drop (VDS) on an LDO power transistor to be maintained at a critical voltage of a saturated area and of a linear area, and ensuring the energy efficiency of a power supply system of the terminal. The method comprises: a terminal determines N LDO in a powered on state of at least one LDO connected to a voltage converter, N being an integer greater than or equal to 1; and the terminal configures an output voltage of the voltage converter on the basis of state information of the N LDO. The state information comprises a load current or an output voltage.
