Part Number: TPS61194

Hi,

According to datasheet P.19, There is no relationship between VIN and VDDIO/EN during power-down.

If there is a time specification for the off of the VIN and VDDIO/EN, could you please let us know?

If the VIN and VDDIO/EN are switched off at the same time, do you have any issue? Please let us know.

Thanks and best regards,
M.HATTORI.

Hi Motoyasu,

We recommend to turn off VIN after internal LDO shutdown, which is around 50us.

If they switch off together, In most cases there should be OK. But as we do not verify it in mass test, we still recommend follow the datasheet.
