产品详情

LT8610特性集，加上：
- 快速输出电流：3.5A（最大值）
- 最短导通时间：30ns
- 提高突发模式效率（仅LT8610AB）
- 增强EMI性能
宽输入电压范围：3.4V至42V
超低静态电流突发模式^®工作：

精确的1V使能引脚阈值
输出软启动和跟踪
小型散热增强型16引脚MSOP封装
通过AEC-Q100汽车应用认证

LT8610A/LT8610AB系列均为紧凑型高效率、高速同步单芯片降压型开关稳压器，瞬态电流功耗仅为2.5μA。与LT8610相比，它们具有较高的3.5A最大输出电流以及较快的30ns最短导通时间。LT8610A与LT8610具有相同的低纹波突发模式性能，而LT8610AB具有较高的轻负载效率。

LT8610的其他特性在LT8610A/LT8610AB系列中保持不变。通过SYNC引脚，可与外部时钟同步。EN/UV引脚具有用于V_IN欠压闭锁或关断的精确1V阈值。启动期间，TR/SS引脚上的电容可对输出电压斜坡速率进行编程。当V_OUT处于编程输出电压的±9%范围内以及发生故障时，PG标志会发出信号。
