Adafruit TPS62827 3.3V Buck Converter Breakout - 3.3V Output 2 Amp Max

This versatile buck converter, powered by the TPS62827, gracefully takes in a 3.4 to 5.5V input and efficiently delivers a 3.3V output, handling up to 2A current. It's ideal for powering demanding 3.3V circuits from a variety of sources, including LiPoly batteries, triple alkaline batteries, and USB power.

Key benefits include compatibility with the LM1117-3.3V TO-220 chip for enhanced performance and a remarkable 90-95% efficiency. The converter features an ENable pin to disable output when needed, perfect for conserving energy in portable projects. Running at a 2.2-MHz fixed frequency, it provides steady performance.

While the chip supports up to 4A, maintaining a 2A constant draw is advisable, with temporary peaks reaching up to 3A. The design includes a robust 2 oz copper double-layer PCB. A header is also included, readily fitting into a breadboard for easy integration. For projects requiring a broader input range, consider the 3.3V output MPM3610 breakout capable of handling up to 20V input.
