  • Commodity Description
德州仪器 UCC28740 恒流反激式控制器是隔离型反激式电源控制器,使用光耦合器来提供恒定电压(CV),改善大型负载阶跃瞬态响应。通过初级侧调节(PSR)技术来完成恒定电流(CC)调节。这些器件可处理来自光耦合器的反馈信息和来自一个二次反激式绕组的信息以实现对输出电压和电流的精确控制。内部 700V 启动开关、动态控制的工作状态和一个定制的调制模式在不牺牲启动时间或输出瞬态响应的同时支持超低待机功耗。UCC28740 所使用的控制算法让运行效率达到或者超过适用标准。UCC28740EVM-525 评估模块是一款 10W 离线不连续模式 (DCM) 反激式转换器,可提供恒定电压 (CV) 和恒定电流 (CC) 输出调节。
