Abstract: A DC-to-DC voltage converter includes a converter input for receiving a DC voltage. A first switch is coupled between the input and a first node. A second switch is coupled between the first node and a ground. An inductor is coupled between the first node and a converter output. A capacitor is coupled between the converter output and ground. An output voltage synthesizer is coupled to the converter input and the converter output for synthesizing the voltage at the first node and for generating a control signal for at least one of the first switch and the second switch in response to the voltages at the converter input and the converter output.

Abstract: A DC-DC converter includes a first differential voltage sensor to detect a first inductor current by sensing a first differential voltage across a first power stage of the DC-DC converter. A second differential voltage sensor detects a second inductor current by sensing a second differential voltage across a second power stage of the DC-DC converter. An integrator stage combines the first differential voltage from the first power stage and the second differential voltage from the second power stage to generate a compensation signal to adjust current balancing for the DC-DC converter.

Abstract: A DC-DC converter has a control circuit for controlling a high-side power transistor and a low-side power transistor connected in series between supply terminals to which an input supply voltage is applied. The converter has a switching node at the interconnection of the power transistors for connection of an inductor to which a load is connected. The control circuit has a feedback loop that provides a pulse width modulated control signal, logic circuitry to which the pulse width modulated control signal is applied and gate drivers with inputs connected to outputs of the logic circuitry and outputs applying gate drive signals to the gates of the power transistors. A digital signal is obtained which is indicative of whether the converter switching node is at a potential above or below a zero reference at the time of the turn-off edge of the low-side gate drive signal.
