Adaptive compensation sytem for switching power converters

Abstract

In an embodiment a DC-DC switching power converter includes a switching circuitry including switches, the switching circuitry configured to receive a DC input voltage and generate a DC output voltage via switching the switches, a switching control circuitry configured to control switching of the switches with a switching signal having a corresponding switching frequency with a corresponding duty cycle, the DC output voltage generated by the switching circuitry depending on the duty cycle, wherein the switching control circuitry is configured to set the duty cycle based on a difference between the DC output voltage and a reference voltage in a closed loop configuration and a compensation network configured to provide stability to an operation of the DC-DC switching power converter, wherein the compensation network has a capacitance having a value depending on the switching frequency.
