DC DC Adjustable Step-Down Converter 0.8V 18V 3A MP1584EN

If you're looking for a high-quality adjustable DC-DC buck converter, this item is for you. This DC-DC Adjustable Step-Down Converter is based on the MP1584 chip, which converts voltages from a range of 4.5V - 28V to a lower rating of 0.8V - 18V. 

Note: Voltage must be 1.5V higher than the desired output. The chip will switch to high-temperature protection mode when it works 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, the minimum is 2A.

Features:

• Wide 4.5V to 28V Operating Input Range
