DC-DC Automatic Step Up-down Power Module (3~15V to 5V 600mA)

This tiny DC-DC buck-boost converter automatically steps voltage up or down to deliver a stable 5 V output from a 3–15 V input. About the size of a coin (17 × 13 mm), it's ideal for embedding in projects where space is tight and a reliable 5 V supply is needed.

With a maximum output current of 600 mA, up to 85% conversion efficiency, and a quiescent current of just 180 µA, this module suits battery-powered and portable applications.
