This work proposes a digital implementation of the Sliding Mode Control law in a DC–DC Buck converter. The control law is implemented monitoring only the DC–DC output voltage, and is capable of producing a maximum overshoot/undershoot of 50 mV for load transients from 0 A to 1.5 A and vice versa. The maximum settling time for these conditions at 1.5% is 5.51 s for a load transient from 1.5 A to 0.15 A. For line transients the DC–DC converter produces minimal overshoot/undershoot. Results are present for the Matlab® model with the continuous control law and for the final implementation using HSim® with the digital control law implementation. The ADC is implemented using a current controlled delay line and it is insensitive to layout parasitics, temperature, supply voltage and process parameters changes. The ADC self calibration capability is considered a major original contribution of this work. The ADC and the digital control where designed using AMS CMOS technology C35B4 (0.35 m).
