High-Current Buck-Boost DC-DC Converter Implemented on PCB

In this paper is presented high-current buck-boost dc-dc converter implemented on PCB. The output voltage VOUT of the converter is regulated to be equal to 12 V. The maximum output current
$I_{OUT(MAX)}$
of the circuit is 5 A. The four-layer PCB is designed using software Cadence OrCAD. The physical PCB sizes of the buck-boost converter are 95mm X 70mm. The efficiency
$\eta$
of the circuit at different output currents
$I_{OUT}$
is evaluated.
