Design a Custom BoardAbout This Component
Adjustable step-down (buck) DC-DC converter IC delivering up to 1.5A output current. Features integrated power switches, PWM control, and adjustable output voltage via external resistor divider. Housed in 8-pin HVSSOP package for space-constrained applications. Suitable for portable electronics, industrial equipment, and consumer devices requiring regulated lower voltage supplies from higher input rails.
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.
