Abstract
A switched mode power supply (SMPS) includes a first switch, a second switch connected, at a switching node, in series with the first switch, and an inductor coupled between the switching node and an output node for providing an inductor current, at the output node. The SMPS also includes an oscillator circuit for providing a clock signal characterized by an oscillating frequency, an adaptive minimum duty-cycle circuit configured to receive an error voltage signal and to generate a current signal to vary the oscillating frequency of the clock signal in response to the error voltage signal, wherein the error voltage signal is based on an output signal at the output node, and a pulse-width modulation (PWM) circuit configured to receive the error voltage signal and the clock signal and to provide a switching control signal to control the first switch and the second switch.
