用于手持设备的升压转换器

MAX8969为设计简单的1A升压转换器，采用小尺寸封装，适用于所有单节锂离子电池供电场合。IC具有保护功能，例如输入欠压锁定、短路保护和热关断等。\n\n 轻载条件下，IC可无缝切换到跳脉冲模式，以提高效率。这种模式下，仅在需要时进行开关操作，通过降低开关频率和电源电流来保持高效工作。\n\n 当输入电压接近输出电压时，为提高效率，提供两种特殊的工作模式：跟踪模式和自动跟踪模式。这些模式允许用户实现静态电流(IQ)与进入boost模式瞬态响应时间之间的平衡。两种模式下，p沟道MOSFET作为限流开关，VOUT保持跟踪VIN。然而，跟踪模式下，关闭boost电路，系统利用E • 灵活的系统集成\n• 输出电流高达1A\n\n• 2.5V至5.5V输入电压范围\n\n• 3.3V至5.7V输出电压范围\n\n\n\n\n• 集成保护提高系统可靠性\n• 欠压锁定(UVLO)\n\n• 短路保护\n\n• 过热关断\n\n\n\n\n• 高效率和低静态电流延长电池寿命\n• 内置同步整流器，效率超过90%\n\n• 自动跟踪模式下的IQ为60µA\n\n• 升压模式下的IQ为45µA\n\n• 跟踪模式下的IQ为30µA\n\n• 关断电流仅为1µA\n\n• 轻载条件下的跳脉冲模式提高效率\n\n• 真关断(True Shutdown™)防止电流从OUT_流;
