Design a Custom BoardAbout This Component
Synchronous step-down converter rated for 4.2V to 80V input with 2A continuous output current and adjustable topology. Features 40µA quiescent current, 200kHz to 2.2MHz switching frequency, integrated synchronous rectification, and cycle-by-cycle current limiting. Suitable for industrial power delivery, wireless infrastructure, and wide-input automotive applications requiring high efficiency and 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.
