Abstract
Enhanced reverse boosting detection in a wireless charging scheme is disclosed. In some implementations, a minimum mid-level input voltage regulation (VMID_MIN regulation) loop is provided to regulate an input voltage from a wirelessly coupled power source when a mid-level of the input voltage falls below a predetermined threshold. The input voltage is provided to a buck converter within a wireless charging receiver. An input missing poller signal generator is provided to generate an input missing poller (IMP) signal if the VMID_MIN regulation loop becomes active and the buck converter has entered a discontinuous mode.
