    • A predictive current feedback system for a switched mode regulator including a sample and hold network for sampling voltage across a lower switch of the regulator and for providing a hold signal indicative thereof, and a predictive current feedback network which adds an offset adjustment to the hold signal based on a duration of a pulse width of a pulse control signal developed by the regulator. Sampling may be done while the lower switch is on for providing a hold value indicative of inductor current while the pulse control signal is low. The offset adjustment may be added to the hold signal in response to a transient event when the pulse signal is high. The offset may be incremental values after each of incremental time periods after a nominal time period, or may be a time-varying value. Adjustment may be made while the pulse signal is low as well.

    • A dynamic voltage response network for a switching regulator with droop control providing a droop control signal includes a voltage identification setting network, a pass and hold system, and a reset network. The voltage identification setting network initiates a hold condition and adjusts an output voltage reference in response to a change in a voltage identification input. The pass and hold system passes the droop control signal during a pass condition and holds the droop control signal during the hold condition. The reset network resets the pass and hold system to the pass condition in response to a reset signal. The reset signal may be provided in response to a variety of conditions, such as load transients, proximity between the developed droop control signal and the held droop control signal, timeout after the output voltage reference is adjusted, among other reset conditions.
