Buck-Boost DC-DC Converter Designed for PCB Applications

In this paper is presented four-switch buck-boost dc-dc converter designed with Cadence OrCAD software tools for printed circuit board (PCB) applications. The output voltage of the converter $V_{OUT}$ is equal to 12 V, while the input voltage $V_{IN}$ can vary from 6.5 V to 36 V. The efficiency $\eta$ of the circuit as a function of input voltage $V_{IN}$ is evaluated. The switching frequency $f_{s}$ of the buck-boost dc-dc converter is equal to 300 kHz. The maximum output power of the circuit is 60 W. The maximum measured efficiency $\eta$ of the converter is equal to 99%.
