A novel stacked step-down switching converter

A new step-down dc-dc converter with one active switch and two diodes is presented. DC analysis is performed and static characteristics are derived, and then device stresses are evaluated and compared to other buck topologies. Design equations are provided, a prototype is simulated and finally experimentally tested. The measurements proved the feasibility of the proposed circuit. This novel converter could be a solution for applications where a small difference between the input and output voltages is needed.
