description

LTC ® 1771是一个高效率电流模式升压式DC / DC控制器，吸引了10μA直流电源在空载时的输出电流调节，同时维持对负载效率高，可达几安培少。 LTC1771驱动外部P沟道功率MOSFET，采用电流模式，恒定关断时间架构。 外部检测电阻器用于方案的工作电流水平。 电流模式控制提供短路保护，出色的瞬态响应和控制启动行为。 突发模式操作，使LTC1771下降到非常低的电流保持高效率。 关断模式，进一步降低电源电流仅为2μA。 对于低噪声应用，Burst Mode操作，可方便地与MODE引脚禁用。 宽输入电源电压范围2.8V至18V（20V最大），使LTC1771理想的电池供电应用中延长电池寿命的多种低压差100％工作周期操作是很重要的。 均采用8引脚MSOP和SO封装，LTC1771的可用性提供了一个最小面积的解决方案。
