Sachin Davangere, Sandeep B V

Abstract: Due to the functionality increase of modern battery powered portable devices, the battery life is an important issue. To extend the battery life, an efficient voltage regulator (VR) is required. In this paper discusses the employment of two-stage architecture on the design of point-of-load (POL) Dc- Dc converters. At first, the paper discusses the benefits of an integrated two-stage stepdown converter with example to clarify the benefits of the design over one-stage approach. The results of two-stage converter are to be compared with the one-stage approach in addition to size and cost reduction. Then, the benefits of replacing boost converters by integrated two-stage step-up converters are discussed followed by a design example for two-stage step-up converter. The circuits are to be simulated and compared with the help of MATLAB/SIMULINK.

Keywords: voltage regulator (VR), point-of-load (POL), MATLAB/SIMULINK
