LM3671 3.3V Buck Converter Breakout 3.3V Output 600mA Max

PRODUCT ID 2745

Your power supply problems just got SUPER SOLVED! 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 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.

There's a 2-MHz fixed-frequency in PWM mode and PFM mode extends the battery life by reducing the current during light load or standby operation.

Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard.
