ABSTRACT

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 η 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 η of the converter is equal to 99%.
