UCC35705和UCC35706器件是8引脚电压模式初级侧控制器，具有快速过流保护。这些器件用作高性能隔离和非隔离电源转换器的核心高速构建模块。
UCC35705 /UCC35706器件具有高速振荡器，具有集成的前馈补偿功能，可提高转换器性能。输出延迟时间为25 ns的典型电流检测可以快速响应过载情况。该IC还提供精确的可编程最大占空比钳位，以增强保护，也可以禁止振荡器以最大可能的占空比运行。
提供两个UVLO选项。具有较低导通电压的UCC35705适用于DC-DC转换器，而UCC35706更高的导通电压和更宽的UVLO范围更适合离线应用。
UCC35705 /UCC35706系列采用8引脚MSOP（DGK），SOIC（D）和PDIP（P）封装。
