Summary:
This paper presents a buck converter which has an high efficient and low power consumption for low power applications. The proposed topology is based on buck converter using switching MOSFET with bulk-terminal. The suitable bulk-terminal switching voltage is selected by analyzing the effect of bulk voltage on a MOSFET performance. It is concluded that the bulk-switched DC-DC buck converter structure has the advantages such as high switching performance, low power consumption and high efficiency compared to conventional DC-DC converter circuits. The efficiency value has obtained 88.2%. The proposed circuit is approved experimentally and simultaneously.
