# LM3671 3.3V Buck Converter Breakout (Component) ## Description LM3671 3.3V Buck Converter Breakout - 3.3V Output 600mA Max. 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 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. ## Component Details - **Owner:** adrian95 - **Created:** 7/13/2022 - **Last Updated:** 4/18/2023 - **Visibility:** Public - **Used in:** 268 projects - **Stars:** 1 - **Forks:** 77 - **Package / Case Code:** 220-TO - **Pin Count:** 4 ## Pins | Pin | Name | Type | |-----|------|------| | - | 3.3V | | | - | EN | | | - | GND | | | - | VIN | | --- *Generated from [https://www.flux.ai/adrian95/lm3671-33v-buck-converter-breakout~g2l](https://www.flux.ai/adrian95/lm3671-33v-buck-converter-breakout~g2l)*
