TPS62480: & TPS82085 EN before VIN

Part Number: TPS62480
Other Parts Discussed in Thread: TPS82085

Hi,

Can you confirm it is OK to have voltage present on EN pin (within recommended op range) before voltage is present on VIN? This question applies to TPS62480 and TPS82085. Looks like it is ok based of datasheet but want to confirm.

Thanks,

Adrian

This should be ok, per each D/S. But we can double-confirm.

Hello Adrian,

I checked for both devices - there is no concern to apply voltage at EN pin before available at VIN.

Best regards,
Ivo
