Abstract
A DC-DC converter is disclosed having an electronic switch network having a supply node, a ground node, an output node, a first inductor node, a second inductor node, and switch control inputs. An inductor is coupled between the first inductor node and the second inductor node. Control logic circuitry has switch control outputs coupled to the switch control inputs, wherein the control logic circuitry is configured to cause the electronic switch network to couple the inductor between the supply node and the output node to provide current flow through the inductor for a fixed time period, and at the end of the fixed time period to measure a check time period until the current flow through the inductor is equal to predetermined current value, and based upon the measured check time period to determine to switch between buck operation and boost operation or boost operation and buck operation.
