Title:
POWER SUPPLY CIRCUIT AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2017/219823
Kind Code:
A1
Abstract:
A power supply circuit (31) and a terminal having the power supply circuit is provided. The power supply circuit comprises: a power supply input module (21), a power supply output module (22), and an adder circuit module (23). The power supply input module is configured to output, according to an adjustment voltage (Vo+Vref) output by the adder circuit module, an operating voltage (Vi) to the power supply output module. The power supply output module is configured to output, according to the operating voltage output by the power supply input module and a reference voltage input by a power supply control signal, an actual operating voltage (Vo) to the adder circuit module. The adder circuit module is configured to add together the actual operating voltage output by the power supply output module and an adder circuit module reference voltage (Vref) to obtain the adjustment voltage and output the adjustment voltage to the power supply input module. The power supply circuit can dynamically enhance power supply efficiency and reduce system power consumption.
