Patent number: 10404217Abstract: Apparatus and methods for reducing inductor ringing of a voltage converter are provided. In certain configurations, a voltage converter includes an inductor connected between a first node and a second node, a plurality of switches, and a bypass circuit having an activated state and a deactivated state. The switches includes a first switch connected between a battery voltage and the first node, a second switch connected between the first node and a ground voltage, a third switch connected between the second node and the ground voltage, and a fourth switch connected between the second node and the output. The bypass circuit includes a first pair of transistors connected between the first node and the second node and configured to turn on to bypass the inductor in the activated state and to turn off in the deactivated state.Type: GrantFiled: March 8, 2018Date of Patent: September 3, 2019Assignees: Skyworks Solutions, Inc., SnapTrack, Inc.Inventors: Peter Harris Robert Popplewell, Jakub F.
