Design a Custom BoardAbout This Component
Power Factor Correction controller for continuous conduction mode step-up pre-converters operating at 72 kHz fixed frequency. Integrates current sensing, PWM control, and comprehensive protection features including overvoltage, undervoltage, overcurrent, and soft-start functions. Designed for offline SMPS applications including flat panel TVs, PC power supplies, and industrial equipment.
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.
