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.

Abstract: Generally speaking, a pulse generation unit can aid load transient response for a DC-to-DC converter. In some examples, a pulse generation unit is coupled to an output voltage of the DC-to-DC converter. The pulse generation unit includes a transient sensing unit and a clock augmentation unit. The transient sensing unit monitors the output of the DC-to-DC converter. When the transient sensing unit detects a load transient, the transient sensing unit generates an additional clock pulse. The clock augmentation unit augments an existing clock signal to include the additional clock pulse.

Abstract: A phase generation circuit is disclosed. The circuit includes a ramp generation circuit arranged to generate a ramp signal in synchronization with a synchronization clock signal. A phase selection circuit generates a reference signal in response to a phase selection signal. A comparator has a first input terminal coupled to receive the ramp signal and a second input terminal coupled to receive the reference signal. The comparator produces a phase clock signal at an output terminal.

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.
