    Abstract: The present disclosure shows ways to use multiple “integrated voltage regulator (IVR) units” to offer IVRs that can cover a wide range of specifications without having to design separate IVRs for different specifications. Instead of designing separate IVRs and paying for separate mask sets for IVRs targeting different specifications (e.g., different design and mask sets for 1 A IVR, 5 A IVR), the disclosed embodiments present ways to design and fabricate large numbers of the same unit IVRs (e.g., 1 A IVR) and decide how many of them to use post-fabrication to deliver different current specifications (e.g., use five 1 A unit IVRs for 5 A, use ten 1 A unit IVRs for 10 A). These disclosed embodiments reduce the mask cost of fabricating IVRs for different specifications and reduce design time by focusing on a single unit IVR.

    Abstract: Systems for charging a battery are provided, the systems comprising: a regulator having an output coupled to the battery and having an input; a wireless charging receiver having an output coupled to the input of the regulator and having an input that receives a power signal from a wireless charging transmitter; a controller having a first input coupled to the input of the regulator, having a second input coupled to the output of the regulator, and having a first output coupled to the wireless charging transmitter, wherein the controller is configured to send, using the first output of the controller, a control signal to the wireless charging transmitter that causes the wireless charging transmitter to change the power signal provided to the wireless charging receiver.

    IPC: H02M3/07 ,  H02M1/088

    Abstract: A voltage regulator comprising: a first regulator module comprising a first transistor switch, wherein the first module operates in a first phase and wherein the first switch is configured to receive a first signal at a first gate of the first switch from a first signal driver; a second regulator module comprising a second transistor switch, wherein the second module operates in a second phase that is different from the first phase, wherein the second switch is configured to receive a second gate drive signal at a second gate of the second switch from a second signal driver, and wherein the second signal is opposite in polarity from the first signal; and a switch that couples the first gate and the second gate during at least part of a time period during which the first switch transitions states and the second switch transitions states.
