该UC3844B，UC3845B系列是高性能固定频率电流模式控制器。 它们是专为Off-Line和DC-to-DC转换器应用设计师提供具有最少的外部元件具有成本效益的解决方案而设计的。 这些集成电路的功能一个振荡器，温度补偿的参考，高增益误差放大器，电流检测比较器和一个高电流图腾柱输出非常适合用于驱动功率MOSFET。
还包括保护功能及组成各具迟滞的输入和参考欠压锁定，逐周期电流限制，锁存为单脉冲测量和触发器的空白，输出关闭所有其他振荡周期，使输出死区时间，以进行编程，从50％至70％。
这些器件采用8脚双列直插和表面贴装（SO-8）塑料包装以及14引脚塑料表面贴装（SO-14）。 该SO-14封装有独立的电源和接地引脚为图腾柱输出阶段。
该UCX844B有（上）的16 V UVLO阈值和10 V（关闭），非常适合离线转换器。 该UCX845B是专为有（ON）和7.6 V（关闭）8.5 V UVLO阈值低电压应用
