Design a Custom BoardAbout This Component
Synchronous step-down switching regulator with 5A output current capability and adjustable output voltage. Integrated high-side and low-side MOSFETs minimize external component count. Features integrated soft-start, current limiting, and thermal shutdown protection. Suitable for point-of-load regulation in computing, telecom, and industrial applications requiring compact footprint with high efficiency.
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.
