  • Publication number: 20250112600
    Abstract: An apparatus includes a first power stage circuit having a first output and a power terminal, and a second power stage circuit having a second output and the power terminal. The apparatus further includes a control circuit having a control input, a first control output, and a second control output. In an example, the control input is coupled to the power terminal, the first control output is coupled to the first output, and the second control output is coupled to the second output. In an example, the control circuit is configured to, responsive to a first voltage at the power terminal being below a threshold voltage, set the first and second outputs to a second voltage.

  • Publication number: 20230318442
    Abstract: A switching converter controller includes a synchronization circuit having a first synchronization circuit input, a second synchronization circuit input, a first synchronization circuit output, and a second synchronization circuit output. The synchronization circuit is configured to: receive an early warning signal at the first synchronization circuit input; receive a load detection signal at the second synchronization circuit input; provide a first control signal at the first synchronization circuit output responsive to the early warning signal; and provide a second control signal at the second synchronization circuit output responsive to the load detection signal. The switching converter controller also includes a driver circuit configured to adjust an idle switch drive signal at a first driver circuit output and a power switch drive signal at a second driver circuit output responsive to the first control signal and the second control signal.

  • Publication number: 20230318455
    Abstract: A transient auxiliary converter includes: a transient auxiliary converter terminal; an inductor having a first side and a second side, the first side of the inductor coupled to the transient auxiliary converter terminal; a capacitor having a first electrode and a second electrode, the second electrode of the capacitor being coupled to ground; a first switch between the second side of the inductor and the first electrode of the capacitor; and a second switch between the second side of the inductor and ground. The first and second switches are operated in accordance with a charge mode and a transient response mode for the transient auxiliary converter. The charge mode builds up charge on the capacitor from charge at the transient auxiliary converter terminal. The transient response mode releases charge on the capacitor to the transient auxiliary converter terminal.
