The solution is based on the EG1162 chip, using a non-isolated synchronous rectifier BUCK architecture to achieve a constant voltage output of 5V20A. This solution uses a double-layer PCB board, with an input voltage range of 9V - 36V (customizable for a wider range), and a maximum efficiency of 94.65%. It features per-cycle current limiting and output short-circuit burst protection, with a compact overall design that may control costs to some extent.
