LTC®3589 是完整的电源管理解决方案,适合于 ARM 和基于 ARM 的处理器、以及高级便携式微处理器系统。该器件包含三个用于内核、存储器和 SoC 电源轨的降压型 DC/DC 转换器、一个用于 I/O (在 1.8V 至 5V) 的降压-升压型稳压器、和三个用于低噪声模拟电源的 250mA LDO 稳压器。一个 I2C 串行端口用于控制稳压器使能、输出电压电平、动态电压调节、操作模式和状态报告。表 1 中概要罗列了 LTC3589、 LTC3589-1 和 LTC3589-2 之间的差异。
稳压器启动的排序操作通过按期望的次序将其输出连接至使能引脚或通过 I2C 端口来完成。系统上电、断电和复位功能受控于按钮接口、引脚输入或 I2C 接口。
LTC3589 支持 i.MAX53/51、PXA 和 OMAP 处理器,具有 8 个处于合适功率级的独立电源轨。其他特点包括接口信号,例如:其电平同时在 4 个电源轨上的编程运行与待机输出电压之间变换的 VSTB 引脚。该器件采用具有裸露衬垫的扁平 40 引脚 6mm x 6mm QFN 封装。
