The control limits fast response duration or impact with respect to the low frequency pole to avoid instability issues. The control may include counters or timers to selectively disable or enable the fast response function. The control can operate based on an error feedback signal and a reference to determine when a fast response should be applied. The resulting power supply system provides robust, well-regulated power, with fast responses to system transients.
