Comparison between Asynchronous and Synchronous Buck Converter Topology

SMPSs are widely used in DC/DC conversions, where the input is a DC. voltage that can be, for example, a battery or fuel cell voltage. In such power conversions, DC/DC converters operate at relatively high switching frequencies, and this enables the use of small inductive components which improve the dynamic behaviour and reduce the size of the converter.This paper basically deals with the comparison of synchronous and Asynchronous Buck topology for mobile applications.In this paper power stage parameters are calculated and we use orcad capture for design and simulation is done in p spice/cadence with the help of Analog behavioral Modeling.
