Design a Custom BoardAbout This Component
Fixed 5V output step-down switching regulator with 3A guaranteed load current and 150kHz switching frequency. Features ±4% output voltage regulation, low standby current, thermal shutdown, and current limiting protection. Requires minimal external components for high-efficiency buck converter applications in power supplies, battery chargers, and pre-regulation circuits.
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.
