Design a Custom BoardAbout This Component
Offline AC-DC switching converter controller for isolated power supplies and adapter applications. Integrates primary-side feedback control with internal MOSFET driver and protections including overvoltage, overcurrent, and thermal shutdown. Suitable for low-power offline applications requiring isolated outputs.
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.
