Abstract
A controller for a switched mode power supply (SMPS) including a reference voltage signal generator to generate a variable reference voltage signal for regulating an output voltage of the SMPS, and a voltage droop control signal generator to receive a current indicator signal indicative of an output current of the SMPS, and generate an output voltage droop control signal in response to a first function and a second function of the current indicator signal. The first function is employed when the reference voltage signal generator ramps the variable reference voltage signal, and the second function is employed thereafter. The controller includes a switching control signal generator to receive a voltage indicator signal, and to generate a control signal to regulate the output voltage of the SMPS based on the voltage indicator signal, the variable reference voltage signal, and the output voltage droop control signal.
