Abstract:
A power supply circuit is provided. The power supply circuit includes an audio codec chip and a voltage absorbing circuit. The audio codec chip has a power input terminal. The power input terminal is connected to a power source terminal. The voltage absorbing circuit is connected between the power source terminal and the power input terminal of the audio codec chip so as to decrease a divided voltage accomplished with a voltage from the power source terminal to low level. A method configured for starting up an audio codec chip on a computer motherboard in a normal manner is also provided.
