LTC3406A 的典型应用 - ThinSOT 中的 1.5MHz、600mA 同步降压稳压器

使用 Analog Devices 的 LTC3406A 的参考设计

设计简介

LTC3406A - 采用 ThinSOT 封装的 1.5MHz、600mA 同步降压稳压器的典型应用。 LTC3406A 是一款采用恒定频率、电流模式架构的高效率单片同步降压稳压器。工作期间的电源电流仅为 20uA，停机时降至 =1uA。 2.5V 至 5.5V 输入电压范围使 LTC3406A 非常适合单节锂离子电池供电的应用。 100% 占空比提供低压差操作，延长便携式系统的电池运行时间。自动突发模式操作可提高轻负载时的效率，进一步延长电池运行时间

说明

Typical Application for LTC3406A - 1.5MHz, 600mA Synchronous Step-Down Regulator in ThinSOT. The LTC3406A is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 20uA, dropping to =1uA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3406A ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery runtime portable systems. Automatic Burst Mode operation increases efficiency at light loads, further extending battery runtime
