WL1837MOD: question about schematic

Part Number:WL1837MOD

Hi,

We've got TI's schematic review as below link. (all threads are locked so I can't make any more reply to that forum.)

Thanks to TI, we succeeded in designing WL1837 to customers' application.

They're going to use 5V for the SW3 in the PMIC.
I think the circuit is wrong and the review is not working well.
So I ask for confirmation. Is SW3 step-up?

Please also inform the following diode specifications.

thanks,

TS
