Abstract
Techniques and apparatus for current-based transitioning between a buck converter mode and a charge pump mode in an adaptive combination power supply circuit. One example power supply circuit generally includes a switching regulator and control logic coupled to the switching regulator. The control logic is generally configured to compare an indication of a current associated with the switching regulator to a threshold and to control a transition of the switching regulator between a buck converter mode and a charge pump mode based on the comparison.
