TPS2560: Unused channel connection

Will Wang47

Part Number: TPS2560

Hi team,

Customer would like to use TPS2560 in their project, they will only use channel 1, for channel 2, does it OK for them to connect EN2 to VIN and leave OUT2 floating with no cap connected?

Thanks and Best Regards,

Will

Hi Ziv,

Thanks for your feedback. I get one question on this:

Since TPS2560 EN is high disable, and why can't just connect to VIN to disable this channel? Any specific reason that we should connect to GND to enable it?

Thanks and Best Regards,

Will

Thanks for reminding Will.

It indeed needs to be pulled up to disable the device as the logic is low to turn on.

Sorry for the mistake.
