用于CCD和LCD的双路输出（正负）DC-DC转换器

MAX685 DC-DC转换器提供低噪声双路输出，为CCD成像设备和LCD供电。该器件使用单个电感来提供独立调节的正负输出。集成电源开关采用小型24引脚4mm x 4mm薄型QFN封装，可节省空间并降低成本。还提供16引脚QSOP封装。\n\n 每个输出可在+2.7V至+5.5V输入电压范围内提供高达10mA的电流。输出电压可独立设置为高达24V和低至-9V。通过一些额外的低成本元件，输出电压可设置为高达45V和低至-16V。输出纹波幅度为30mVp-p。MAX685采用220kHz或400kHz固定频率、脉宽调制(PWM)控制方案，可进行输出噪声滤波并减小外部元件的尺寸。该频率还可 • 双路输出使用单个电感\n\n• 低噪声输出，30mVp-p纹波\n\n• 输出电压高达24V，低至-9V（添加元件后高达45V，低至-16V）\n\n• 内部开关采用小型24引脚4mm x 4mm薄型QFN封装\n\n• 220kHz/400kHz固定频率PWM工作模式\n\n• 频率可与外部时钟同步\n\n• 电源正常指示器\n\n• 可选上电时序\n\n• 逻辑控制关断电流：0.1µA;
