TPS61230A: Rise speed of Vin

Part Number: TPS61230A

Does TPS61230A have any constraints on the rise speed of Vin?

I want to use TPS61230A with Vin whose rise speed is 0.8V/1mS, will any issues arise?

Hi Chikara,

Your slew rate of 0.8V/ms is very slow. I don't see any issue.

Best Regards,

Travis

Hi Travis,

Thank you for your prompt reply.

Has too late slew ever caused any issue?

Thanks & Best Regards,

Hi Chikara,

I don't see any issue unless you care about the total start up time, because the device will not start up until vin>2.5V.

Best Regards,

Travis

Hi Travis,

Thank you for your reply.

I don’ｔ care the total start up time,I was concerned that TPS61230A work unusually due to the slow slew rate.

Thanks & Best Regards,
