Title:
POWER SUPPLIER CIRCUIT, CONTROLLING METHOD AND ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2019/205071
Kind Code:
A1
Abstract:
A power supplier circuit, a controlling method and an electronic equipment. The power supplier circuit includes: a converting circuit, configured to convert input voltage to output voltage, the converting is controlled by a controller of the converting circuit, current flowing through a startup resistor provides startup current to the controller for starting the controlling; an input voltage detector, configured to detect the input voltage is DC (Direct Current) voltage or AC (Alternative Current) voltage; and a startup controlling circuit, configured to control the startup current provided to the controller, according to detecting result of the input voltage detector. Therefore, the power supplier could work when input voltage is DC voltage, and avoid turn off flicker when input voltage is AC voltage.
