Abstract

In operation of a flybuck converter, a first output capacitor is charged and, after this charging, charge is transferred from the first output capacitor to a second output capacitor. The charge transferring includes closing a switch to establish a first current path through which the first output capacitor discharges current that induces, in a second current path, current that charges the second output capacitor. While the switch is closed during the charge transfer, a current limit condition in the switch is detected. In response to detection of the current limit condition, the switch is opened, and is thereafter closed again before attempting to charge the first output capacitor again, thereby to resume transferring charge from the first output capacitor to the second output capacitor.
