TIDA-00701 是 100W、24V 工业交流-直流电源,旨在用于过程控制、工厂自动化和机械控制等工业和仪器系统。
TI Designs The TIDA-00701 design is a 100-W, 24-V, 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 has a front-end power factor correction (PFC) circuit designed using the UCC28051 PFC controller, followed by 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 and 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 are
• Reduced component count design to achieve NEC Class-2 and Limited Power Source (LPS) norms
• Meets ENERGY STAR® Rating, the 2013 EU ecodesign directive Energy-related Products (ErP) Lot 6, and stringent current THD norms
• Robust output supply protected for output overcurrent, output short-circuit, output overvoltage, and over-temperature conditions
