Other Parts Discussed in Thread: TPS62A06
Hi,
We found TPS62A06 abnormal star up before EN<1.2V, is it normal?
Any condition may cause Vout early rise up?
Thanks!
Jeff

Hi Jeff,
Yes, this is how it should work. You must drive EN above 1.2V to ensure that EN is high. But normally, it will be high below 1.2V.

Hi Chris,
Got it, but do you have TPS62A06 TYP and MAX data?
Our customer need tuning the timing sequence,
Thanks!
Jeff
No, this is not specified and can vary greatly based on the device or temperature, etc.
They should not rely on non-specified parameters to tune their timing. They need to make sure their system works with the specified timings. Can I help with that?

Hi Jeff,
The lowest logic high voltage, per the D/S, is 0.4V.
I can discuss your specific case via email.
