Design a Custom BoardAbout This Component
Adjustable boost/SEPIC converter with integrated high-side and low-side MOSFETs for regulated voltage supplies. Supports input voltages from 2.7V to 30V with programmable output via external resistor divider. Commonly used in battery-powered systems, LED drivers, and applications requiring both step-up and inverting topologies in a compact 8-pin package.
Package: MSOP-8 · 8 pins
Why does this need a breakout?
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
