I'm using an LT8645S with an output of 24V in a battery powered setup.
For higher efficiency the BIAS pin is tied to the board supply of 3.3V which is independent from the LT8645S and always on.
If the 24V are not needed the LT8645S is put into shutdown.
Is there a significant current via the BIAS pin DURING SHUTDOWN in addition to the quiescent current via VIN or is there only a small leakage current?
Thanks in Advance
