Design a Custom BoardAbout This Component
Synchronous buck converter with adjustable output voltage from 0.8V to 5.5V at up to 2A output current. Features integrated MOSFETs, operates from 4.5V to 18V input, and includes soft-start and current limit protection. Ideal for point-of-load regulation in battery-powered devices and industrial applications requiring compact, efficient power conversion.
Package: QFN-16 (3×3mm) · 16 pins
Why does this need a breakout?
This 3×3mm QFN with 0.5mm pitch requires a breakout board to hand-solder reliably—the fine pitch and sub-millimeter pad spacing make direct assembly impractical without professional equipment. The breakout converts the hidden pads to accessible 0.1" spaced pins, enabling breadboard prototyping of energy harvesting and battery management circuits.
