Design a Custom BoardAbout This Component
Adjustable synchronous buck regulator with integrated FETs, capable of 3.5A continuous output current. Operates from 4.5V to 28V input with output voltage adjustable via external resistor divider. Includes integrated soft-start, thermal shutdown, and current limit protection. Suitable for power supply applications requiring compact, efficient DC-DC conversion.
Package: SOIC-8-1EP (3.9×4.9mm, EP) · 8 pins
Why does this need a breakout?
8-pin SOIC with exposed pad is difficult to hand-solder reliably due to tight 1.27mm pitch and thermal management requirements. A breakout board brings pins to standard 0.1" spacing for breadboard prototyping while providing proper pad routing and thermal dissipation for audio amplifiers and gate drivers.
