电流跳闸阈值和谷电流跳闸阈值。ISET引脚打开时，峰值电流比较器的小阈值为540mA。谷电流比较器的小阈值为峰值电流的50%，即270mA。在大负载时，电感器电流在峰值和谷值电流阈值之间倾斜，这导致大负载电流为两者的平均值，即405mA。对于需要较少电流的应用，峰值电流阈值可降低至140mA，从而提供100mA的平均输出电流。此较低峰值电流允许针对较低电流应用优化效率和组件选择。对于需要大于400mA的应用，可以使用FBO引脚并联连接多个LTC7138。有关更多信息，请参阅更高电流应用部分。峰值电流阈值与ISET引脚上的电压成线性比例，280mV和1V分别对应140mA和540mA峰值电流。谷电流阈值随着ISET引脚上的电压相应地改变，以保持在编程峰值电流的50%。该引脚可由外部电压源驱动以调制峰值电流，这在某些应用中可能是有益的。通常，峰值电流通过ISET引脚和接地之间适当选择的电阻器（RISET）编程。产生的电压current trip threshold and the valley current trip threshold. With the ISET pin open, the peak current comparator has a minimum threshold of 540mA. The valley current comparator has a minimum threshold of 50% of the peak current, or 270mA. At maximum load, the inductor current ramps between the peak and valley current thresholds, which results in a maximum load current that is the average of the two, or 405mA. For applications that demand less current, the peak current threshold can be reduced to as low as 140mA, which provides 100mA average output current. This lower peak current allows the efficiency and component selection to be optimized for lower current applications. For applications that require more than 400mA, multiple LTC7138s can be connected in parallel using the FBO pin. See the Higher Current Applications section for more information. The peak current threshold is linearly proportional to the voltage on the ISET pin, with 280mV and 1V corresponding to 140mA and 540mA peak current, respectively. The valley current threshold correspondingly changes with the voltage on the ISET pin to remain at 50% of the programmed peak current. This pin may be driven by an external voltage source to modulate the peak current, which may be beneficial in some applications. Usually, the peak current is programmed with an appropriately chosen resistor (RISET) between the ISET pin and ground. The voltage generated
