Design a Custom BoardAbout This Component
High-voltage flyback switching regulator IC with integrated 700V power FET for offline power conversion. Provides constant-voltage and constant-current output regulation without optical coupler, achieving ±5% accuracy. Supports up to 115kHz switching frequency with valley switching and frequency dithering for EMI compliance, typical in wall adapters, LED drivers, and auxiliary power supplies.
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.
