Texas Instruments UCC28740 | 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. The key highlights of reference design:>Reduced component count design to achieve NEC Class-2 and Limited Power Source (LPS) norms>Meets Energy Star Rating and 2013 EU eco-design directive Energy-related Products (ErP) Lot 6>Robust output supply protected for output over-current, output short circuit, output over-voltage, and over temperature conditions
