AAT1153IDE-0.6-T1集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

AAT1153IDE-0.6-T1属于集成电路（IC）的稳压器-DC-DC开关稳压器。由美国思佳讯公司制造生产的AAT1153IDE-0.6-T1稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。

General Description

The AAT1153 SwitchReg™ is a 1.2MHz constant frequency current mode PWM step-down converter. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90 efficiency during peak load conditions. The AAT1153 also can run at 100 duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications.
