TPS61165: TPS61165 Dimming issue.

Part Number: TPS61165

Hi Sir,

Our customer used the TPS61165 for panel Backlighting,
If the system is go to S3/S4/S5 Short time,then fast Wake up.
Maybe is under 3 second Wake up.
Thery are found out TPS61165 can't use the Dimming function.
But we can see the input VIN/CTRL are function normal.

If the system go to S3/S4/S5 over 3~5minutes , then wake up  system the TPS61165 Function work is OK. 

the excell is our Pass & Fail waveform for your reference.

the customer schematic is copy TI datasheet.

Do you have any suggest for this case?
