8V-14V，550mA LNB电源和控制电压稳压器

MP8125是一款电压稳压器，它通过DiSEqC 1.x兼容链路从专用控制器接收指令，通过同轴电缆为卫星接收器的RF LNB（低噪声模块）变换器提供高效低噪声电源。MP8125集成了电流模式升压稳压器和跟踪线性稳压器。升压调节器提供干净且安静的电源，不会污染下发至接收器的低噪声RF信号。跟踪线性稳压器具有输出过载保护或短路保护。MP8125提供欧洲EUTELSAT规范（DiSEqC）中规定的多种功能，包括通过电压选择LNB水平或垂直极化方向，以及长同轴电缆上压降的VOUT补偿选择。根据DiSEqC标准，其内部振荡器会产生一个22kHz单频（tone）信号，并可通过EXTM引脚将其激活或禁用。 • DiSEqC 1.x兼容性\n• 高达 550mA 的输出电流\n• 输入电压范围：8V至14V\n• 带内部开关的升压变换器\n• 低噪声LDO输出\n• 内置 22kHz 单频信号发生器\n• 可调电流限制\n• 1V 线路压降补偿\n• 可调软启动时间\n• 电源正常（POK）指示\n• 短路保护\n• 热保护\n• 带裸露焊盘的TSSOP16封装和24引脚4mm x 4mm QFN封装;
