Design a Custom BoardOffline switching regulator controller for flyback topology applications. Features integrated primary-side control with cycle-by-cycle current limiting and output voltage feedback regulation. Suitable for compact AC-DC power supplies up to 65W, with 8-pin SOIC packaging for cost-effective board integration.
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.
