Title:
VOLTAGE STABILIZING CIRCUIT, VOLTAGE STABILIZING METHOD, CHARGING CIRCUIT, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/141551
Kind Code:
A1
Abstract:
A voltage stabilizing circuit (100), a voltage stabilizing method, a charging circuit (90, 200), and an electronic device. By designing the voltage stabilizing circuit (100) having multiple operating modes, a structure in which a boost conversion circuit (93) and a buck-boost conversion circuit (94) are simultaneously provided is avoided, so that the efficiency of voltage conversion is improved, and costs are reduced.
