Design a Custom BoardAbout This Component
TinySwitch-4 energy-efficient off-line switcher IC for flyback power supplies delivering 8.5W at 230VAC or 6W at universal input. Features 725V rated MOSFET, line-compensated overload power, self-biasing, and integrated thermal shutdown with auto-restart. Ideal for compact adapters and chargers 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.
