LMR23625-Q1: External bias is applied to the output

Part Number:LMR23625-Q1

Hi,

We got a question from the customer about LMR23625-Q1.
Could you help us?

[Question]
When the IC operates under the following condition, the external bias is applied to the output. Are there any concerns for these usage?

 Part Number=LMR23625CF-Q1 *FPWM option
 Vin=8~16V
 Vout=5V
 Iout=max 1.8A
 fsw=460kHz by external clock

 - Case 1
   They are thinking the small current flows through from 5.5V to the output. It should be OK.

 - Case 2
They are thinking the output voltage will be 5.5V and low side FET turn on to discharge from output capacitor in this condition. They are concerned the possibility to damage the IC.

Best Regards,
