300W 9A Adjustable DC-DC Step-Down Buck Converter Power Supply Module

This 300W 9A Adjustable DC-DC Step-Down Buck Converter Power Supply Module allows you to step down an input voltage of 5V-40V DC and set the output to 1.2V-35V. The output voltage will be lower than the input voltage.
It uses a dedicated benchmark IC and high-precision current sensing resistor. It can also make a more stable constant current and High output current. The max output current can reach 9A. Low output ripple. The high frequency capacitor reduces output ripple. Suitable for LED driver.

We recommend enhanced cooling when operated at an environmental temperature greater than 40C or when the load wattage is greater than 50W. Adding fuses or protection circuit at the input port would be great.
