Design a Custom BoardAbout This Component
LinkSwitch-TN integrated offline switcher IC featuring a 700V power MOSFET for buck, buck-boost, and flyback topologies. Delivers up to 225mA output current in discontinuous conduction mode or 360mA in continuous mode across 85-265VAC input range. Includes built-in current limiting, thermal protection, and frequency jittering for reduced EMI, making it an energy-efficient replacement for linear and capacitor dropper supplies in low-power applications.
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.
