  • Publication number: 20250119053
    Abstract: The present application relates to a DCDC circuit, a circuit start-up method, and an electronic device. The DCDC circuit includes a transformer circuit, a synchronous rectification circuit, and a control circuit; wherein the control circuit is configured to control a turn-on duration of a first switch and a turn-on duration of a second switch in a first bridge circuit of the transformer circuit to increase progressively every switching cycle until an output voltage of the transformer circuit is greater than a first target voltage; and control a turn-on duration of a third switch and a turn-on duration of a fourth switch in a second bridge circuit of the synchronous rectification circuit to increase progressively every switching cycle until an output voltage of the synchronous rectification circuit is greater than a second target voltage.

  • Publication number: 20240030819
    Abstract: Provided are a switch control circuit and method, and an electronic device. The switch control circuit includes a voltage conversion module and a control module. The voltage conversion module operates, based on a received input voltage, in at least one of a boost mode, a buck mode and a buck-boost mode. The control module controls switching frequencies of first, second, third and fourth switches of the voltage conversion module. In the boost mode, the first and third switches are switched, at a first switching frequency, between an on-state and an off-state, and the second and fourth switches are switched, at a second switching frequency larger than the first switching frequency, between the on-state and the off-state. In the buck mode, each of the first and third switches is switched at the second switching frequency, and each of the second and fourth switches is switched at the first switching frequency.
