TPS61023: Is output isolated when disabled ?

David Guest1

Part Number: TPS61023

Tool/software:

Is the output isolated in shutdown or does the input voltage appear at the output ?

Another question is why such high saturation current inductors are specified in datasheet, I would have thought 2A-3A would be sufficuent

Hi David,

The output is isolated in shutdown.

For the Isat of inductor, you may refer to the following formula in "8.2.2.2 Inductor Selection" in datasheet and make sure that the Isat is greater than the IL(P) in all the work conditions in your application. There is no need to select a inductor with Isat as big as that in the datasheet table 8-2.

Regards

Lei
