Design a Custom BoardAbout This Component
Synchronous buck regulator with adjustable output voltage, rated for 5A continuous current. Features integrated MOSFETs, PWM control, and wide input voltage range. Commonly used in automotive, industrial, and consumer applications requiring efficient DC-DC conversion with minimal external components.
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.
