Hi TI,

Would you like share more information when LM5146 work in standby mode?

What voltage and current will output when EN/UVLO was during 0.4V~1.2V?

Hi Cayden,

When EN/UVLO voltage is in this intermediate state, VCC will be up but there will be no switching, and thus no energy delivered to the output. What you show from the pin descriptions table also describes this.

Regards,

Tim

So there will no output when EN/UVLO is 0.4~1.2V.

Thanks Timothy.
