UCC3800 General Description

The UCC3800 is a standout choice among the UCC280x family of integrated circuits for its high-speed, low-power capabilities. With all the necessary control and drive components built-in, this chip simplifies the design of off-line and DC-to-DC power supplies while maintaining a minimal parts count. Its compatibility with the UCx84x family's pin configuration makes it easy to integrate into existing systems, and the added features of internal soft start and leading-edge blanking offer additional control and protection

Key Features

Soft start for reliable startup
Fault tolerance for robust operation
Blanking of leading edges
High accuracy voltage reference
