Our customer is thinking to use LM5118-Q1 in following condition.
Vin: Min 2.3V, Typ 24V, Max 60V
Vout: 7V
Iout: 1A
Vin operating range is 3V to 75V, thus 2.3V is lower than the range.
Then they thought using method as the following circuit. Can this circuit operate? Do you have any concern?
I checked this circuit with LM5118EVM at default condition. However it didn't operate normally. It seemed that LM5118 detect current limit, so it couldn't keep Vout voltage.
Please let me know the better way if you have.
