The application of the sliding-mode control theory to the regulation of dc-to-dc switching converters is reviewed. Subsequently, linear dynamical models are derived and compensating networks are designed. An analog integrated circuit illustrating the theory has been designed, implemented and applied to regulate a buck converter in continuous conduction mode. Experimental verifications are provided.

Keywords: Sliding-mode control, compensating networks, integrated circuit controller.
