Abstract: In described examples of a ramp circuit, a first terminal of a capacitor is coupled to a ramp terminal and a second capacitor terminal is coupled to a return terminal. A charge source has an input terminal coupled to a supply terminal and a charge output terminal. A resistor has a first terminal coupled to the return terminal. A first switch is coupled between the ramp terminal and a second terminal of the resistor. A second switch is coupled between the charge output terminal and the ramp terminal.

Abstract: A switch-mode power supply circuit includes a low-side switching transistor, a high-side switching transistor, a low-side current sensing circuit, and a gate driver circuit. The low-side current sensing circuit is coupled to the low-side switching transistor and is configured to sense a current flowing through the low-side switching transistor. The gate driver circuit is coupled to the low-side current sensing circuit and the high-side switching transistor. The gate driver circuit is configured to generate a signal having a first drive strength to switch the high-side switching transistor based on current flowing through the low-side switching transistor being less than a threshold current, and to generate a signal having a second drive strength to switch the high-side switching transistor based on current flowing through the low-side switching transistor being greater than the threshold current. The first drive strength is greater than the second drive strength.

Abstract: A system includes an input voltage supply and advanced current mode (ACM) converter device coupled to the input voltage supply. The ACM converter device (102) includes a pulse-skipping mode (PSM) transitions controller configured to switch between PSM and discontinuous conduction mode (DCM). The system also includes an output inductor coupled to a switch node of the ACM converter device. The system also includes an output capacitor with a first terminal coupled to the output inductor and a second terminal coupled to a ground node. The system also includes a voltage divider in parallel with the output capacitor, where the voltage divider is configured to provide a feedback voltage to the ACM converter device.

Abstract: In a power converter system, circuitry generates first and second PWM signals during a PWM cycle for controlling application of power to an inductor. Circuitry generates error signals having AC- and DC-components, the error signals being generated in response to indications of the power applied to or developed by the inductor. Circuitry generates a feedback control signal in response to the error signals. The first and second PWM signals are controlled in response to the feedback control signals.
