数据: UCC180x, UCC280x, UCC380x Low-Power BiCMOS Current-Mode PWM Controllers 数据表
UCCx80x系列高速,低功耗集成电路包含离线和DC-DC所需的所有控制和驱动组件固定频率电流模式开关模式电源,器件数量最少。
这些器件具有与UCx84x系列相同的引脚配置,并且还提供内部全周期软启动和内部引线的附加功能 - 电流检测输入的边沿消隐。
UCCx80x系列提供多种封装选项,温度范围选项,最大占空比选择以及临界电压电平选择。较低的参考部件(如UCC2803和UCC2805)最适合电池供电的系统,而UCC2802和UCC2804的较高参考电压和较高的UVLO迟滞使其成为离线电源的理想选择。
UCC180x系列的工作温度范围为-55°C至125°C,UCC280x系列的工作温度范围为-40°C至85°C,UCC380x系列的工作温度范围为0°C至70°C。 °C。
