Design a Custom BoardAbout This Component
Step-down switching regulator with adjustable output voltage from 1.2V to 37V at up to 3A output current. Operates from input voltages up to 40V with integrated power switch and current-limiting protection. Commonly used in battery charging, industrial equipment, and general DC-DC conversion applications requiring compact packaging and high efficiency.
Package: TO-263-2 · 3 pins
Why does this need a breakout?
This SMD package requires a breakout board to interface with breadboards and standard prototyping layouts. The three-pin configuration with large copper pad underneath demands reflow soldering or careful hand-soldering to avoid cold joints, making a breakout board with standard 0.1" headers essential for reliable connections. Ideal for power regulators and MOSFETs where thermal performance and ease of iteration matter.
