产品详情

70W, Solar Energy Harvester with Maximum Power Point Regulation

LT®3763 是一款固定频率、同步降压型 DC/DC 控制器,专为准确地调节高达 20A 的输出电流而设计。平均电流模式控制器将在 0V 至 55V 的宽输出电压范围内保持电感器电流调节作用。输出电流由 CTRL 引脚上的模拟电压和一个外部检测电阻器设定。电压调节和过压保护利用一个连接于输出和 FB 引脚之间的分压器来设定。开关频率可通过 RT 引脚上的一个外部电阻器或利用 SYNC 引脚和一个外部时钟信号在 200kHz 至 1MHz 的范围内进行设置。输入和输出电流检测可提供输入电流限制和这些电流的准确测量。FBIN 引脚可供那些需要峰值功率跟踪功能的应用之用。
