Texas Instruments UCC28740DR | Demoboard TIDA-00702

Beschreibung

The TIDA-00702 is a 60-W, industrial AC-DC power supply designed for use in industrial and instrumentation systems such as process controls, factory automation, and machinery control. This reference design is a Quasi-resonant (QR) flyback converter implemented using the UCC28740 CC-CV flyback controller with optocoupled feedback for voltage and primary-side regulation (PSR) for constant current regulation, with all the necessary protections built-in. Hardware is designed and tested to pass conducted emissions, surge, and EFT requirements.
