startup delay of LM43602

Other Parts Discussed in Thread: LM43602

Hello,

We need to delay the power up of LM43602 switching regulator by ~1 sec. Can we use an RC of 500K & 10uF on "EN" pin ?

Will there be any latch-up issue on LM43602 during turn-off sequence ? Suppose during turn-off the voltage on VCC falls down below 3V immediately and voltage on EN pin takes about ~1 sec to arrive at 3 due to high cap (10uF), will there be any issue ? will there be a quick & safe discharge path from "EN" ?

Datasheet mentions that voltage on EN should be max "VIN+0.3V"

Below is the schematic of LM43602, R89 will be replaced to ~500K & R77 will be replaced by 10uF.

Kindly have a detailed look on our request as we are at critical stage of program and your support will be appreciated.

Thankyou.
