Wireless charging module, electronic equipment and charging control method

Abstract

The invention discloses a wireless charging module, an electronic device and a charging control method, the wireless charging module comprises a first step-down circuit, a second step-down circuit, a wireless charging resonance circuit and a controller, the first step-down circuit and the second step-down circuit are both used for receiving an input voltage, reducing the input voltage into a direct-current voltage, and sending the direct-current voltage to the controller; a second direct-current voltage output by the second step-down circuit is different from a first direct-current voltage output by the first step-down circuit, and the power consumption when the second step-down circuit outputs the second direct-current voltage is lower than that when the first step-down circuit outputs the first direct-current voltage and the second direct-current voltage; the wireless charging resonance circuit charges the powered device based on the received direct-current voltage; the controller determines a current state, generates a control signal based on the state, and controls the target step-down circuit to provide a DC voltage for the wireless charging resonance circuit based on the control signal, the target step-down circuit is a first step-down circuit or a second step-down circuit, and the state comprises a charging state and an uncharged state.
