Design a Custom BoardAbout This Component
LinkSwitch-TN offline switcher IC integrating a 700V power MOSFET, oscillator, and control circuitry for low-cost buck converter applications. Delivers up to 120mA (MDCM) or 170mA (CCM) output current from universal 85-265VAC input with integrated auto-restart fault protection and thermal shutdown. Ideal for LED drivers, appliances, and industrial control supplies requiring minimal external components.
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.
