UCC3813-x器件系列的高速，低功耗集成电路包含离线和DC-所需的所有控制和驱动器组件这些器件具有与UC384x器件系列相同的引脚配置，并提供内部全周期软启动的附加功能，这些器件具有最少的器件数量。-p>
这些器件具有与UC384x器件系列相同的引脚配置。电流检测输入的内部前沿消隐。
UCC3813-x器件系列提供多种封装选项，温度范围选项，最大占空比选择和关键电压电平选择。具有较低参考电压的器件（如UCC3813-3和UCC3813-5）最适合电池供电系统，而UCC3813-2器件和UCC3813-4器件的较高基准电压和较高的UVLO迟滞使其成为断电时的理想选择。 - 线电源。
UCC2813-x器件系列的工作温度范围为-40°C至85°C，UCC3813-x器件系列的工作温度范围为0°C至70°C 。
