Design a Custom BoardAbout This Component
Adjustable synchronous step-down buck converter rated for 3A output current in a compact 8-pin PowerPAD package. Operates from 4.5V to 42V input with external resistor divider for 0.8V to 15V adjustable output. Suitable for automotive, industrial, and telecom applications requiring high efficiency 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.
