在TPS54331的datasheet第九页计算UVLO电阻的时候有个Ven-is the enable threshold voltage of 1.25v,没有明白这个意思。究竟是1.25V还是这个滞环的门限值比如0.2V?谢谢！
这是一个使能信号，当该脚的电压大于1.25V的时候芯片才能工作
Please refer to the datasheet:
Enable pin. Pull below 1.25V to disable. Float to enable. Programming the input undervoltage lockout with
two resistors is recommended.
