| description | The invention provides electronic equipment, which comprises a buck-boost converter, a mode control module, a low dropout linear regulator and a plurality of loads, and the plurality of loads comprise at least one camera and other loads except the at least one camera; the mode control module is used for acquiring the working states of the plurality of loads, and the working states comprise a first state in which at least one camera works and a second state in which no camera works; when the working state is a first state, the mode control module provides a first control signal for the buck-boost converter; the buck-boost converter is used for switching a working mode into a pulse width modulation mode under the control of the first control signal. The power supply ripple of the pulse width modulation mode is relatively small, so that the influence of the power supply ripple on the camera can be eliminated, and the problem that dark fringes appear when the camera shoots in dark light is solved.
