Description
XL4005 5 A Step-Down Voltage Converter
This XL4005-based DC-DC buck converter reduces a higher input voltage to an adjustable lower output. The source states it can provide 3.5 A / 50 W, and up to 5 A / 75 W when fitted with a heatsink. These are stated maxima; actual power depends on voltage, cooling and operating conditions.
