Design a Custom BoardAbout This Component
Adjustable step-down buck converter IC rated for 3A output current in 8-pin PowerPad surface-mount package. Features integrated high-side and low-side MOSFETs with typical input range up to 36V and adjustable output voltage set via external resistor divider. Suitable for automotive and industrial power supply applications requiring compact form factor and 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.
