说明

TPS61094 是具有超级电容器管理的 60nA IQ 升压转换器。该器件可为智能仪表和超级电容器备用电源应用提供电源解决方案。

TPS61094 具有宽输入电压范围和高达 5.5V 的输出电压。当 TPS61094 在降压模式下为超级电容器充电时,可通过两个外部电阻器对充电电流和终止电压进行编程。当 TPS61094 在升压模式下工作时,可使用一个外部电阻器对输出电压进行编程。

在自动降压或升压模式下(EN = 1,MODE = 1),施加输入电源后,该器件会将输入电压旁路到输出,同时还能为备用超级电容器充电。当输入电源已断开或低于输出目标电压时,TPS61094 将进入升压模式,并通过备用超级电容器调节输出电压。TPS61094 在此模式下消耗 60nA 静态电流。

TPS61094 支持真关断模式(EN = 0,MODE = 1)和强制旁路模式(EN = 0,MODE = 0)。在真正关断模式下,TPS61094 将负载与输入电源完全断开。在支持强制旁路模式时,TPS61094 通过旁路开关直接将负载连接到输入电压并且仅消耗 4nA 电流,从而延长电池寿命。
