Design a Custom BoardAbout This Component
Fixed-output buck switching regulator delivering 5V at up to 3A from higher input voltages. Features integrated power switch, PWM controller, and current limiting for robust DC-DC conversion. Commonly used in power supply designs, battery-powered systems, and embedded applications requiring efficient voltage step-down.
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.
