Hello E2E,
I hope all is well. Are there any restrictions on using an RC filter from Vin to EN on the TPSM82810? Are there corner cases that could cause issues if the RC is too big? What about too small?
Related question. Is there a diode from EN to Vin? From the abs max table, it appears that there is not a diode, otherwise the abs max would likely be Vin + 0.3Vin for Ven. Instead it is 6.5V. Can you confirm? If there is a diode, it can cause an issue on shutdown since Ven could be larger than Vin and held up by the cap... Having the R would help provide a discharge path, though I'd like to avoid any issues if at all possible.
Thank you!
Russell
