The embodiment of the invention provides a voltage conversion circuit. The voltage conversion circuit comprises at least two stages of conversion sub-circuits which are connected in sequence, the first stage of conversion sub-circuit is connected to the control voltage output end of a power input circuit and an integrated circuit chip, and the input ends of the other conversion sub-circuits are connected to the output end of the upper stage of conversion sub-circuit; the first-stage conversion sub-circuit is used for receiving a first chip control voltage output by the power supply input circuit and a delay signal output by the integrated circuit chip, and converting the first chip control voltage into a second chip control voltage under the control of the delay signal; the second chip control voltage is output to a next-stage conversion sub-circuit; and the other conversion sub-circuits are used for converting the second chip control voltage to output a target chip voltage. According to the voltage conversion circuit, the voltage conversion circuit is simple in structure, low in cost and good in performance, and the span of voltage conversion of each stage is small.
