低电压、降压型DC-DC转换器，SOT23封装

MAX1733/MAX1734均为降压型DC-DC转换器，输出电压可低至1.25V，输出电流超过250mA。这些转换器使用专有限流控制方案，可实现更高效率，达到90%以上。这些器件的静态电源电流非常低(40µA)，并且具有1.2MHz（最大值）的较高工作频率，可使用低成本的小型外部元件。上述特性组合使MAX1733/MAX1734非常适合空间受限应用，能够完全高效替代线性稳压器。\n\n 内部同步整流极大地提高了效率，并消除了传统降压转换器所需的外部肖特基二极管。两款器件均配备内部数字软启动功能，可在启动时限制输入电流，并降低输入电容要求。\n\n MAX1733提 • 250mA保证输出电流\n\n• 配备同步整流器，效率达到90%以上\n\n• 微型5引脚SOT23封装\n\n• 静态电源电流：40µA\n\n• 0.01µA逻辑控制关断\n\n• 开关频率高达1.2MHz\n\n• 固定1.8V或1.5V输出(MAX1734)\n\n• 可调输出电压(MAX1733)\n\n• 初始精度：±1.5%\n\n• 输入范围：2.7V至5.5V\n\n• 通过软启动限制启动电流;
