US Patent 10180695 Dropout recovery with overshoot and inrush current reduction

In a power management device, a hiccup mode is implemented by using, for example, a counter to count the number of cycles for which a current limiting event has occurred and forcing the power management device to hiccup when a certain number of current limiting events have been counted. A soft start circuit is typically employed to ramp up the output voltage when the power management device is turned back on. By resetting the soft start voltage to the feedback voltage of the load of the power management device upon the first detection of a current limiting event, hiccup can be avoided because resetting the soft start voltage to the feedback voltage will reduce the current in proceeding cycles thereby avoiding additional current limiting events.
