Design a Custom BoardAbout This Component
Offline switching regulator IC for multiple-output AC-DC power supply applications. Features integrated high-voltage switch, designed for compact power factor correction and isolated output designs. Operates from universal AC input with internal gate drive and cycle-by-cycle current limiting in 8-pin surface mount 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.
