产品详情资料
这些规格由特定的操作条件、电路板布局、额定封装热阻抗和其他环境因素决定。注4:该IC包括过热保护,旨在在瞬时过载条件下保护设备。当该保护激活时,将超过高额定结温。在规定的对高工作结温度以上连续运行可能会损害设备可靠性或损坏设备。超温保护等级未经生产测试。注5:由于在开关频率下传输栅极电荷,动态电源电流更高。请参阅应用程序信息。LTC7138 4 7138f有关更多信息,请访问www.linear.com/LTC7138典型性能特性峰值电流和谷值电流跳闸阈值vs RISET效率vs负载电流,VOUT=5V峰值电流和谷值电流跳闸门限vs温度和ISET效率vs负载电流,VOUT=3.3V峰值电流与谷值电流阈值vs输入电压效率vs负载电压,VOUT=1.8V效率vs输入电压,VOUT=5V反馈比较器跳闸阈值vs温度RUN和OVLO阈值vsspecifications is determined by specific operating conditions in conjunction with board layout, the rated package thermal impedance and other environmental factors. Note 4: This IC includes overtemperature protection that is intended to protect the device during momentary overload conditions. The maximum rated junction temperature will be exceeded when this protection is active. Continuous operation above the specified absolute maximum operating junction temperature may impair device reliability or permanently damage the device. The overtemperature protection level is not production tested. Note 5: Dynamic supply current is higher due to the gate charge being delivered at the switching frequency.
