Which circuit has the lowest quiescent current when the main device EN/UVLO is NOT ENABLED, the LM34936 buck-boost converter or TPS25982 eFuse?

Thanks,

Hi Carl,

When the LM34936 buck-boost converter is not enabled, the maximum shutdown current is 10uA, with an average of 2.6uA. When the TPS25982 eFuse is in shutdown, it draws a maximum of 20uA, and an average of 3.67 uA.

You can find this in the datasheets below under criteria of "Shutdown current"
