MP1584 DC-DC 3A Step Down Module

MP1584 DC-DC 3A Step Down Module converts input voltage between 4.5V and 28V into a smaller voltage between 0.8V and 18V, capable of driving a 3A load with excellent line and load regulation.This makes the fully compatible with setups from 2-6s. Simply turn the small screw to adjust the voltage.

These are perfect where space is a factor, or you don't want to add a whole PDB just to get 5v. Input must be >1.5V higher than output! The chip will get to high temperature protection mode when it work at a high-power conversion, without any cooling, it is able to output 3A current at 5V. But at higher output voltage, the current output capacity is lower than 3A, approx 2A.
