TPS61150A / output timing of ISET voltage

Hi,

I'd like to ask about output timing of ISET pin voltage(1.229V,typ).

I think the ISET voltage outputs when SEL1/2(both or either) is high, not only supply Vin .

(1) Is it correct?

(2) Does ISET voltage output immediately from SEL1/2 is high?

Yes, the ISET will keep low until SEL is high.

For Q.2, let me give you an example:

If the SEL1 is high, then ISET2 will be high immediately after SEL2 is high, If the SEL1 is low, then there will be a several microseconds delay before ISE2 get high after SEL2 is high.
