用于软启动电路的 LTC3615HFE-1 双路 3A 同步降压
DC/DC 转换器的典型应用。 LTC3615-1 是一款双路 3A 同步降压稳压器，采用电流模式、恒定频率架构。
直流电源电流仅为 130 uA（空载突发模式操作），同时保持输出电压，在关断时降至零电流。 2.25V 至 5.5V 输入电源范围使这些器件非常适合单锂
离子电池应用

Typical Application for LTC3615HFE-1 Dual 3A Synchronous Step-Down DC/DC Converter for Soft-Start Circuit. The LTC3615-1 is a dual 3A synchronous step-down regulators using a current mode, constant-frequency architecture. The DC supply current is only 130 uA (Burst Mode operation at no-load) while maintaining the output voltages, dropping to zero current in shutdown. The 2.25V to 5.5V input supply range makes the parts ideally suited for single Li-Ion applications
