产品详情资料

该引脚的输出将在电容器上产生平滑的电压斜坡。如果该斜坡速率低于内部1ms软启动，则输出电压将受到SS引脚上斜坡速率的限制。内部和外部软启动功能在启动时、输入电源发生欠压或过压事件后以及超温停机后重置。峰值电感器电流编程峰值电流比较器标称将峰值电感电流限制为610mA。该峰值电感器电流可通过将电阻器从ISET引脚接地来调节。通过电阻器从该引脚输出的5µA电流产生一个电压，用于调整峰值电流比较器阈值。谷电流阈值跟踪峰值电流阈值设置，通常为峰值电流的60%。在睡眠模式下，ISET管脚的电流降至1µA。退出休眠模式后的个开关周期，ISET电流增加回5µA。睡眠模式下的ISET电流减少，以及从ISET引脚到地添加滤波网络RISET和CISET，提供了一种以较低效率和略微退化的负载阶跃瞬态响应为代价减少轻负载输出电压纹波的方法。对于需要更高输出电流的应用，LTC7138提供反馈比较器输出引脚（FBO），用于组合多个of this pin will create a smooth voltage ramp on the capacitor. If this ramp rate is slower than the internal 1ms soft-start, then the output voltage will be limited by the ramp rate on the SS pin. The internal and external soft-start functions are reset on start-up, after an undervoltage or overvoltage event on the input supply, and after an overtemperature shutdown. Peak Inductor Current Programming The peak current comparator nominally limits the peak inductor current to 610mA. This peak inductor current can be adjusted by placing a resistor from the ISET pin to ground. The 5µA current sourced out of this pin through the resistor generates a voltage that adjusts the peak current comparator threshold. The valley current threshold tracks the peak current threshold setting, and is typically 60% of the peak current. During sleep mode, the current sourced out of the ISET pin is reduced to 1µA. The ISET current is increased back to 5µA on the first switching cycle after exiting sleep mode. The ISET current reduction in sleep mode, along with adding a filtering network, RISET and CISET, from the ISET pin to ground, provides a method of reducing light load output voltage ripple at the expense of lower efficiency and slightly degraded load step transient response. For applications requiring higher output current, the LTC7138 provides a feedback comparator output pin (FBO) for combining the output current of multiple
