Key Features

  • Great for supplying power to hungry 3.3V voltage circuits from a range of battery or power options
  • Runs at 2.2-MHz fixed-frequency
  • Takes up to 5.5V input and provides a 3.3V output with up to 2A current
  • "Pin compatible" with the LM1117-3.3V TO-220 chip

This little buck converter based on the TPS62827 is super handy, taking up to 5.5V input and providing a 3.3V output with up to 2A current. It's great for supplying power to hungry 3.3V voltage circuits from a range of battery or power options. This chip provides up to 2 Amp load current across the entire input voltage range of 3.4 to 5.5V. It's not a huge range but does cover LiPoly batteries, 3 alkalines, and USB power.

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.

The Adafruit TPS62827 Breakout runs at 2.2-MHz fixed-frequency. Even though the chip itself supports up to 4A, we found that 2 Amps or so was a good max to stick to for constant current draw and 3 Amps for temporary peak current draws. We did use a 2 oz copper double-layer PCB.
