Patent abstract

Circuits and methods to mitigate or eliminate potentially damaging events (e.g., damaging current spikes from in-rush current, charge transfer current, short circuits, etc.) in DC-DC power converters. Embodiments enable dynamic switching of conversion ratios in reconfigurable power converters while under load without turning off the power converter circuitry or suspending switching of the charge pump power switches. Embodiments selectively increase the ON resistance, R
