Abstract: In one example, a controller circuit is configured to: receive a first measurement signal representing a power converter input voltage; receive a second measurement signal representing a power converter output voltage; receive an indication of whether a voltage across a switch is positive during a state change of the switch; based on the first and second measurement signals and the indication, determine: a charging interval; a first dead time interval after the charging interval; a discharging interval; and a second dead time interval after the discharging interval; and provide a first control signal at the first control output, and provide a second control signal at the second control output, in which the states of the first and second control signals vary across the charging interval, the first and second dead time intervals, and the discharging the interval.

Abstract: An apparatus includes a resonant converter controller having a converter voltage sensing terminal, a reference voltage terminal, a converter current sensing terminal, first and second converter capacitor terminals, and first and second control outputs. The resonant converter controller is configured to: receive a current sensing signal at the converter current sensing terminal; generate a first signal based on the current sensing signal; generate a second signal representing a difference between a first voltage at the converter voltage sensing terminal and a reference voltage at the reference voltage terminal; and generate first and second switching signals at, respectively, the first and second control outputs responsive to the first signal, the second signal, and a capacitor voltage between the first and second converter capacitor terminals to regulate the first voltage based on the reference voltage.

Abstract: The present disclosure generally relates to integrated devices with a conductive barrier structure. In an example, a semiconductor device includes a substrate, a conductive barrier structure, a channel layer, a barrier layer, a gate, and a conductive structure. The substrate is of a first semiconductor material. The conductive barrier structure is on the substrate. The channel layer is of a second semiconductor material and is on the conductive barrier structure. The barrier layer is on the channel layer, and the channel layer is between the barrier layer and the conductive barrier structure. The gate is over the barrier layer opposing the channel layer. The conductive structure is electrically coupled between the conductive barrier structure, the channel layer, and the barrier layer.

Abstract: In described examples, an integrated circuit includes first and second current sources, first and second switches, a dV/dt phase detector, a control circuit, and source, gate, and drain terminals for coupling to, respectively, a source, gate, and drain of a power FET. The first switch is coupled between the first current source and the gate terminal. The second switch is coupled between the second current source and the gate terminal. The dV/dt phase detector detects a dV/dt phase of the power FET and outputs to the control circuit. The control circuit controls the first and second switches to perform a turn-on sequence of the power FET, including: closing the first switch while keeping the second switch open; and after receiving a signal from the dV/dt phase detector indicating the dV/dt phase has started, opening the first switch, and closing the second switch.
