Is there a requirement that the EN pin of the LT8642S must be stable before VIN is applied? I am simulating a 1V, 6A regulator circuit using LTSPICE and I see that if the EN pin is not Up before applying VIN, the regulator does not produce any output. If I generate EN signal before VIN signal, the regulator functions correctly.
Is this the issue with Simulation or does the chip really behaves this way?
