Operation of buck regulator with ultra-low input voltage

[摘要] Based on the LTC3621 and LTC3624, the designed buck regulator proposed in this thesis aims to lower the allowed input voltage and increase efficiency compared to the original part without making significant changes to quiescent current and part performance. This thesis will discuss additions and modifications made to the original afformentioned parts in order to achieve said goal. This thesis will provide an in depth analysis through simulations of the results of the changes made and a comparison of performance between the original and the redisigned part.
