具有增强控制逻辑、温度范围为 -40°C 至 85°C 的相移全桥控制器

UCC3895 是一款相移 PWM 控制器，它通过相移切换一个半桥相对于另一半桥来实现对全桥功率级的控制。该器件支持恒定频率脉冲宽度调制和谐振零电压开关，可在高频下提供高效率。该器件既可用作电压模式控制器，也可用作电流模式控制器。\n\nUCC3895 在保留了 UC3875/6/7/8 系列和 UC3879 的功能的同时，还改进了该控制器系列，使其具有增强的控制逻辑、自适应延迟设置和关断 功能 等附加功能。由于该器件采用 BCDMOS 工艺制造，因此与双极型同类器件相比，它的工作电流要小得多。UCC3895 的最大时钟频率为 1MHz。 • 可编程输出接通延迟\n• 自适应延迟设置\n• 双向振荡器同步\n• 电压模式、峰值电流模式或平均电流模式控制\n• 通过单个引脚实现可编程的软启动、软停止和芯片禁用\n• 0% 至 100% 占空比控制\n• 7MHz 误差放大器\n• 工作频率高达 1MHz\n• 500kHz 下典型工作电流为 5mA\n• UVLO 期间具有 150µA 的极低工作电流;
