升/降压型DC-DC转换器，QSOP封装

MAX1672集成带线性稳压器的升压型DC-DC转换器，提供升压/降压转换。该器件以高于和低于输出电压的可变输入提供恒定输出电压。其输入范围为1.8V至11V，预设输出范围为3.3V或5V。还可以使用两个电阻将输出设置为1.25V至5.5V。典型效率为85%。\n\n MAX1672采用升压/线性稳压器配置，与竞争的SEPIC和反激式配置相比，可使用单个体积更小的电感。开关电流也可选，支持在低电流应用中使用更小的电感器。线性稳压器还充当滤波器来降低输出纹波电压。\n\n MAX1672的静态电源电流低至85µA，在逻辑控制的关断模式下会进一步降至0.1µA。关断模式 • 升压/降压转换\n\n• 输入范围：1.8V至11V\n\n• 3.3V/5V或可调输出电压范围\n\n• 输出电流：\n• 5V时为300mA (VIN > 2.5V)\n\n• 5V时为150mA (VIN > 1.8V)\n\n\n\n\n• 电感相比SEPIC和反激式配置更小\n\n• 关断模式下负载与输入断开\n\n• 电池电源电流：\n• 85µA（空载）\n\n• 0.1µA（关断）\n\n\n\n\n• 反PGI/PGO低电池电量比较器\n\n• 16引脚QSOP封装（与8引脚SO封装尺寸相同）\n\n• 无需外部FET\n\n• 热保护和短路保护;
