DC-DC Automatic Step Up-down Power Module (2.5~15V to 3.3V 600mA)

This compact DC-DC buck-boost converter automatically steps voltage up or down to deliver a stable 3.3 V output from a wide 2.5–15 V input range. With a maximum output current of 600 mA and ultra-low 180 µA quiescent current, it's perfect for battery-powered projects and embedded systems that need a reliable 3.3 V rail.

The module's tiny 17 × 13 mm footprint makes it easy to embed into custom designs. It operates at up to 1.2 MHz switching frequency for efficient conversion, with stable output voltage that won't drift over extended operation.
