Adafruit MPM3610 3.3V Buck Converter Breakout - 21V In 3.3V Out at 1.2A

This buck converter, based on the MPM3610, excels at transforming up to 21V input into a steady 3.3V output with a current capacity of up to 1.2A. It's perfectly suited for delivering power to 3.3V circuits from various battery or power sources.

The ability to handle input voltages from 4.5 to 21V distinguishes this converter from many others, which typically cap at around 6 VDC. Optimized for portability, it is "pin compatible" with the LM1117-3.3V TO-220 chip, offering improved performance and efficiency (90-95%). An ENable pin allows you to shut down the output completely by connecting it to low.

The Adafruit MPM3610 Breakout operates at a 2-MHz fixed-frequency in PWM mode, with a compact and highly efficient design featuring a fully integrated inductor. Each unit is delivered with a fully assembled and tested breakout board, complemented by headers for easy breadboard integration.
