LTC3406AB-2 采用 ThinSOT 封装的 2.25MHz、600mA 同步降压型稳压器
LTC®3406AB-2 是一款高效率单片式同步降压型稳压器，采用一种恒定频率、电流模式架构。无负载时的电源电流为200μA，并在停机模式中降至 <1μA。2.5V 至 5.5V 的输入电压范围使得 LTC3406AB-2 成为单节锂离子电池供电型应用的理想选择。100% 占空比实现了低压差操作，从而延长了便携式系统中的电池使用寿命。对于那些对噪声敏感的应用，执行 PWM 脉冲跳跃模式操作可提供非常低的输出纹波电压。
开关频率在内部设定为 2.25MHz，因而允许使用小的表面贴装型电感器和电容器。内部同步开关提高了效率，并免除了增设一个外部肖特基二极管的需要。利用 0.6V 反馈基准电压能够容易地对低输出电压提供支持。LTC3406AB-2 采用扁平 (高度仅 1mm) ThinSOT 封装。至于那些需要执行突发模式 (Burst Mode®) 操作的应用，请查阅 LTC3406A 的相关资料。
