Abstract: A power converter system for converting an input voltage at an input into an output voltage at an output may comprise a switch network comprising a reactive circuit element and a plurality of switches, switch control circuitry configured to operate the plurality of switch in a plurality of periodic, sequential states to regulate the output voltage, and reference current generating circuitry. The reference current generating circuitry may include a comparator coupled to a sensed switch of the plurality of switches and configured to compare a current flowing through the sensed switch to a reference current and current-steering circuitry coupled to the comparator configured to generate the reference current and alternate the reference current between a first reference current and a second reference current whenever the switch control circuitry changes from one state of the plurality of periodic, sequential states to another state of the plurality of periodic, sequential states.

Abstract: Methods and apparatus for controlling a switch transition in an inductive switching circuit are disclosed. A switch driver is configured to receive an indication of current through a diode associated with a first switch and dynamically control a switch transition of a second switch based on the indication of current, so as to reduce the switch transition time, when possible, whilst maintaining a voltage transient due to the switch transition within an acceptable range.
