5pcs MP1584 5V Fixed Output 3A DC Step Down Converter Buck Module 4.5-28V Input

This ultra-small buck step-down voltage regulator is surprisingly powerful for it's size. Synchronous rectification is more efficient and creates less waste heat which allows it to reach current ratings found in regulators many times it's size. Despite the small size and low price, this power regulator delivers on it's specs. The output voltage is fixed at 5V and cannot be adjusted. Compared to adjustable regulators, the fixed output saves time and ensures accuracy. Be careful not to exceed the input voltage or maximum output current. Do not back feed power through the module.

Do not apply reverse polarity voltage.

5V fixed output non-isolated DC buck voltage regulator, ultra small module 22x17x4mm
