Design a Custom BoardAbout This Component
PWM-based LED driver regulator IC in 8-pin VSSOP package. Features integrated control circuitry for driving LEDs with adjustable brightness via PWM modulation. Designed for low-power LED applications requiring compact form factor and efficient power management in space-constrained designs.
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.
