摘要：
In this paper a transient suppression method applicable to integrated DC-DC converter is introduced. This method is designed for point-of-load applications where load current frequently varies. An auxiliary buck stage is added to a traditional buck stage that turns on only during transient to assist sinking or injecting load current. This helps swiftly to restore the output voltage to steady state and reduce transient variation. Simulation shows that for a 3W, 12V to 1V buck converter, this method effectively suppress the overshoot to be less than 3% when subjected to a 3A to 0A transient. This represents a 30% reduction in output voltage variations during transient comparing to control methods that only focus on fast recovery.
