LM26480: Plan to tie EN to Vin, do I still have to worry about the 8ms delay?

Jerome Villapando

Part Number: LM26480

Do we need an RC to make sure the delay is happening? I saw another post where they recommend a 1uF cap but I don't think the trace resistance will be high enough to achieve 8ms delay.

Hello Jerome,

Yes the VIN must be stable for 8ms before setting EN pin high. You can use RC delay or some active component to realize the delay.

Thanks.
