3 说明

TPSM8287Axx 是具有差分遥感和 I2C 接口的引脚对引脚直流/直流降压电源模块系列。该电源模块集成了同步降压转换器、电感器和输入电容，可简化设计、减少外部元件并节省印刷电路板 (PCB) 面积。该设计采用紧凑的薄型封装，旨在通过标准表面贴装设备进行组装。TPSM8287Axx 系列实现了可支持快速瞬变的增强型控制方案。TPSM8287Axx 可以在固定频率或省电模式下工作。遥感功能可优化负载点的电压调节，并且该器件可在整个温度范围内实现 ±0.8% 的直流电压精度。这些器件可在堆叠、并联模式下运行，以提供更高的输出电流或将功耗分散到多个器件上。I2C 兼容接口提供多种控制、监控和警告功能。可通过 VSETx 引脚选择启动电压，以便在没有实际 I2C 通信的情况下实现上电。
