Texas Instruments UCC28063 PFC控制器
德州仪器UCC28063 Natural Interleaving™ 具有改进可闻噪音抗扰的转换模式功率因数校正控制器,适用于对可闻噪音消除要求较高的消费电子应用。TI的这个解决方案将转换模式的优势 – 采用低成本元件实现高效率 –扩展到更高的、以前不可能的额定功率级别。使用Natural Interleaving技术,TI UCC28063的两个信道都作为主信道工作并以相同频率同步。这种方法先天可以实现强大的匹配,带来更快的响应,确保各通道都工作于转换模式。经过拓展的系统级保护可提供输入欠压与掉电恢复、输出过压、开环、过载、软启动、相位故障检测、和热关断等功能。另有故障安全(FailSafe)过压保护功能,可防止对中间电压短路造成的损坏,如果未检测出这种短路,有可能造成灾难性的器件故障。特性
