Abstract :
A voltage regulator (VR) design with improved efficiency especially at light load and with good steady-state ripple and dynamic performance is discussed in this paper. The presented VR utilizes a proposed "pulse-sliding" load adaptive control scheme to satisfy the VR requirements. Such VR design is important in many applications including those that are battery powered and has energy consumption constrains. In this paper, the concept, design, analysis, simulation and experimental circuit of the improved VR design are presented
