Design a Custom BoardAbout This Component
LinkSwitch-TN offline switcher IC integrating a 700V power MOSFET, oscillator, and current-limit control for efficient buck converter applications. Delivers 120mA typical output at 230VAC in MDCM mode with integrated auto-restart protection and frequency jittering for EMI reduction. Ideal replacement for linear and capacitor-dropper supplies in LED drivers, appliances, and industrial controls.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
