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: A method and apparatus for extending the driving capacity of a power management device are provided. The method involves determining an energy requirement for the operation of a power management device. Next, the method compares the energy requirement for the operation of a power management device with a capability of a first power device. If the energy requirement is greater than the energy requirement of the first power device, the energy is switched to a second power device of higher capacity. The apparatus includes: a first power device; a second power device connected in parallel to the first power device; a first inductor connected to the first power device and a capacitor connected to the first inductor; and a second inductor connected to a second power device and a capacitor connected to the second inductor.

Abstract: A method and apparatus for a boost converter topology for low battery voltage support. In the method, an input voltage is boosted by closing first through third switches and then opening a fourth switch to charge a capacitor. The first and second switches are then opened. The voltage is then doubled by closing the third and fourth switches to discharge the first capacitor into a second capacitor and charging a third capacitor. A further embodiment provides an additional method for selectively boosting an input voltage to an electronic device. The method first characterizes the efficiency of a circuit, and then determines a crossover point for a ratio of output voltage to input voltage, and then enabling or disabling a voltage boost converter based on the crossover point.
