Hi everyone, I would like to know your insights about the functions of SHDN, ENOUT and FLT pin in LT4363 this is a surge protection IC. I copies the circuit in the typical application since I am also using a 28V input.

I should let this float or maybe connect it to somewhere or maybe mark as unconnected??

Send help.

Thank you!

My reference with this is a MPS ic which they uses MOSFET transistor. BTW, this is LTM8053/LTM8053-1 a step-down module regulator.
hi,
I have downloaded the LTM8053 d/s.
Do you have a circuit diagram showing how what you have connected to the MPS to the PG output pin.?

actually this is not my circuit this is only my reference sir, and the IC that they are using her is from MPS while I am planning to use IC from ADI, and in the MPS they already stated in their datasheets on how to use the PGOOD pin.

hi hass,
I don't want to guess, when will you have your final circuit to post, so that I can give you a meaningful answer.?

hi hass,
I will look over the usage of PGOOD, but I would like to see your idea's on how it may be used.
Is this a College assignment?
