Design a Custom BoardAbout This Component
PWM buck converter controller IC in 8-pin VSSOP surface-mount package. Operates at up to 8V input with integrated gate drive and current-sense circuitry for efficient step-down DC-DC conversion. Suitable for low-power applications requiring compact form factor and minimal external components.
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.
