Abstract: The present disclosure includes circuits and methods for driving resonant actuators. In one embodiment, a drive signal is applied to an actuator during a portion of a plurality of half cycles of a period of the drive signal. The actuator has a resonant frequency and may vibrate in response to the drive signal. An induced voltage is generated on terminals of the actuator in response to the vibration. A detection circuit may detect when the induced voltage on the actuator crosses a threshold after the drive signal is turned off. The drive signal may be triggered based on when the induced voltage crosses the threshold to align a frequency and phase of the drive signal with the resonant frequency and a phase of the actuator.

Abstract: Techniques for efficiently generating a power supply are described. In one design, an apparatus includes an envelope amplifier and a boost converter. The boost converter generates a boosted supply voltage having a higher voltage than a first supply voltage (e.g., a battery voltage). The envelope amplifier generates a second supply voltage based on an envelope signal and the boosted supply voltage (and also possibly the first supply voltage). A power amplifier operates based on the second supply voltage. In another design, an apparatus includes a switcher, an envelope amplifier, and a power amplifier. The switcher receives a first supply voltage and provides a first supply current. The envelope amplifier provides a second supply current based on an envelope signal. The power amplifier receives a total supply current including the first and second supply currents.; In one design, the switcher detects the second supply current and adds an offset to generate a larger first supply current than without the offset.

Abstract: The present disclosure includes circuits and methods for controlling skin temperature of an electronic device (100). In one embodiment, a thermal sensor (150) is configured on a case of a handheld electronic device. The thermal sensor is coupled to a battery charger (110) having a current limit circuit. If the sensed temperature of the case increases above a threshold, a current limit is reduced to reduce current in the battery charger.
