Description:

This DC-DC switching buck converter is capable of driving a 5A load with excellent line and load regulation. The main switching component is XL4015, an adjustable output version switching regulator. It is an efficient switching regulator and the output efficiency is significantly higher in comparison with the popular boost regulators. At higher input voltages, the regulator operates at a switching frequency of 180kHz, thus allowing the overall board size to be smaller and space-saving. It is a high-power switching module with a toroidal ring inductor.
