LTC3624 / LTC3624-2 - 具 3.5μA 静态电流的 17V、2A、同步降压型稳压器
LTC®3624 / LTC3624-2 是一款高效率 17V、2A 同步单片式降压型稳压器。开关频率固定至 1MHz (LTC3624) 或 2.25MHz (LTC3624-2)，具有一个 ±40% 的同步范围。稳压器具有超低的静态电流，并可在宽 VOUT 范围内实现高效率。
该降压型稳压器在 2.7V 至 17V 的输入电压范围内运作，并可在输送高达 2A 输出电流的同时提供一个介于 0.6V 和 VIN 之间的可调输出范围。这些器件还提供了一个用户可选模式输入，以使用户能在纹波噪声和轻负载效率之间做出权衡；突发模式操作可在轻负载条件下提供最高的效率，而脉冲跳跃模式则可提供最低的电压纹波。另外，MODE 引脚还可用于使开关频率同步至一个外部时钟。
