Design a Custom BoardAbout This Component
Synchronous step-down switching regulator with 3A output current capability and adjustable output voltage. Operates from 4.5V to 36V input with integrated power MOSFETs for high efficiency. Suitable for industrial and automotive applications requiring compact, regulated power 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.
