说明

TPS65023x 器件 是一种集成式电源管理 IC,适用于 由一节
锂离子或锂离子聚合物电池供电并需要多个电源轨的应用。TPS65023x 器件具有三个高效的降压转换器,用于在基于处理器的系统中提供内核电压、外设、I/O 以及存储器电源轨。内核转换器可通过串行接口实现动态电压变化,从而使系统实现动态节能。这三个降压转换器会在轻负载时进入低功耗模式,从而在可能的最宽负载电流范围内实现最高效率。

TPS65023x 还集成了两个可通过外部输入引脚启用的通用 200mA LDO 稳压器。每个 LDO 可在 1.5V 至 6.5V 输入电压范围内正常运行,从而使得它们可以由其中一个降压转换器供电,也可以由电池直接供电。用户可使用 DEFLDO1 和 DEFLDO2 引脚通过数字方式将这两个 LDO 的默认输出电压设置为四个不同的电压组合。串行接口可用于动态电压调节和屏蔽中断,或用于停用、启用和设置 LDO 输出电压。该接口符合快速模式和标准模式 I2C 规格,可实现高达 400kHz 的传输频率。TPS65023x 采用 40 引脚 WQFN 封装,并在 –40°C 至 85°C 的自然通风温度范围内运行。
