LTC®3608 是一款高效率、单片式同步降压型 DC/DC 转换器,能够从一个 4V 至 18V (最大值为 20V) 输入电源来提供高达 8A 的输出电流。它采用一种谷值电流控制架构,以在高频条件下提供非常低占空比的操作,并实现超卓的瞬态响应。工作频率由一个外部电阻器来选择,并针对 VIN 和 VOUT 中的变化进行补偿。

在轻负载条件下,可以把 LTC3608 配置为执行不连续操作或强制连续操作。强制连续操作可降低噪声和 RF 干扰,而不连续模式则能够通过减少轻负载条件下的开关损耗来提供高效率。

故障保护功能由内部折返电流限制、一个输出过压比较器和一个可选的短路停机定时器来提供。用于电源排序的软起动功能利用一个外部定时电容器来实现。稳压器电流限值可由用户来设置。当输出处于调节状态时,一个电源良好输出电压监视器将发出指示信号。LTC3608 采用紧凑型 7mm x 8mm QFN 封装。
