低电压、400mA、降压型DC-DC转换器，SOT23封装

MAX1920/MAX1921降压型转换器可输出最低1.25V的电压，同时提供超过400mA的电流。这两个转换器使用独特的限流控制技术可获得高于90%的效率。这两个器件具有超低静态工作电流(50µA)、高达1.2MHz (最高)的开关频率，允许选用小尺寸、低成本的外部元件。这些特点使MAX1920/MAX1921在空间受限应用中成为线性稳压器出色的、高效替代品。\n\n 内置同步整流极大地改善了效率，无需使用传统降压型转换器中所必需的外部肖特基二极管。两个器件还包括内部数字软启动，用于限制启动过程的输入电流、降低对输入电容的要求。\n\n MAX1920提供可调输出 • 保证400mA输出电流\n• 内置同步整流，效率>90%\n• 小巧的6引脚SOT23封装\n• 高达1.2MHz开关频率，小尺寸的外部元件\n• 50µA静态工作电流\n• 0.1µA逻辑控制关断电流\n• 2V至5.5V输入电压范围\n• 固定1.5V、1.8V、2.5V、3V和3.3V输出电压(MAX1921)\n• 可调输出电压(MAX1920)\n• ±1.5%初始精度\n• 软启动限制启动电流;
