Abstract
The present disclosure provides a soft-start power supply circuit, a method for controlling the same, and a display device. The soft-start power supply circuit includes: a soft-start circuitry configured to pull up a potential of a feedback voltage terminal to a potential of an input voltage terminal during a first phase of an operating cycle and to pull down the potential of the feedback voltage terminal to a potential of a ground terminal during a second phase of the operating cycle; a feedback operation circuitry configured to control a driving circuitry to be turned off during the first phase and control the driving circuitry to be turned on and off alternately during the second phase; a driving circuitry configured to, in an on state, output a signal of the input voltage terminal after rectifying and filtering by a rectifying and filtering circuitry to an output voltage terminal.
