Design a Custom BoardAbout This Component
Adjustable synchronous step-down DC-DC converter delivering up to 3A output current. Features integrated high-side and low-side MOSFETs with PWM control for efficient power conversion. Suitable for battery-powered applications, industrial equipment, and consumer electronics requiring compact regulators with minimal external components.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
