A feedback loop in a variable power supply has an adjustable response speed based on operating conditions of the power supply. The response speed can be increased upon encountering a transient to improve response performance to the transient. A response speed control for the control loop modifies or bypasses a major low frequency pole in a compensation network in the control loop to increase response speed. 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.
