# LM3671\(Module\) (Component)

## Description

This 3\.3V Buck Converter Breakout board is great for supplying power to low voltage circuits from a single Li\-Ion cell battery or USB power\.  This chip provides up to 600\-mA load current across the entire input voltage range of 3\.5 to 5\.5V\.  Great for your portable project, we made this "pin compatible" with the LM1117\-3\.3V TO\-220 chip so you can swap it in for better performance \(90\-95% efficiency\!\) There's also an ENable pin, tie it low to shut down the output completely\.
