5V至3.3V输出同步降压型电源控制器

MAX767是一款高效、同步降压控制器IC，专用于将5V固定电源转换为严格调节的3.3V输出。有两个关键特性将该器件与类似的低压降压型开关稳压器相区别：高工作频率和应用电路中的全N沟道结构。300kHz的工作频率使得外部表面贴装元件体积非常小且成本低。\n\n 3.3µH电感用于5A电流，其物理尺寸至少比竞争解决方案中的电感小五倍。全N通道结构和同步整流可降低成本并提高效率。在宽负载范围内效率超过90%，无需散热。输出电容要求较低，从而节省了电路板空间和成本。\n\n MAX767是一款单片BiCMOS IC，采用20引脚SSOP封装。对于其他固定输出电压和封装选项 • 效率：>90%\n\n• 静态电源电流：700µA\n\n• 待机电源电流：120µA\n\n• 输入范围：4.5V至5.5V\n\n• 低成本应用电路\n\n• 所有N通道开关\n\n• 小型外部元件\n\n• 紧缩小型封装(SSOP)\n\n• 预先设计的应用：\n• 标准5V至3.3V DC-DC转换器，电流高达10A\n\n• 高精度Pentium P54C VR规格电源\n\n\n\n\n• 可用的固定输出电压：\n• 3.3V（标准）\n\n• 3.45V（高速Pentium™）\n\n• 3.6V (PowerPC™);
