Abstract

Abstract: The synchronous Buck converter is used to step down voltage from higher to lower level. Now a days, Efficiency is the major concern in designing any converters hence power converter design must be optimized to increase the performance of converter and to meet the requirement of load demand. The proposed work aims at design and Implementation of 6W synchronous buck converter using LT3845 synchronous step-down controller IC which is suitable for High Efficiency application. The compactness of device is also a major concern for proposed work, hence the current mode topology makes the power converter module more compatible and efficiency. The proposed work is designed for output power 12V/0.5A(6W) for an Input voltage from 24-30V.The system frequency of converter is 150Khz.The results are obtained for Hardware Implementation using LT3845 IC.
