Hi,

Could you tell me about TPS61093　startup sequence.
Customer is trying to start up in the following order.

1.EN pin high
2.VIN pin voltage applying

Is it safe to ''voltage applied to EN before VIN?

Best regards,

it should be safe if the EN is not higher than the maximum voltage. but i'll double confirm with EVM

it is OK that the EN voltage is applied before VIN.
