TPS92075: Output current too high.

Part Number: TPS92075

Hi,

This is my first time working with the TPS92075, so I am not familiar with what issues can arise, etc. I am seeing an interesting issue. 

The output current is supposed to be 150mA but I am measuring 171mA. I didn't run the driver for more than a few minutes but it also seems that the output current is slightly fluctuating. At first it was measuring at about 161mA but after a few minutes it rose to 171mA.

I know this could be related to the layout but I would like to eliminate schematic/circuit errors first. 

I am not really sure what the issue here could be. Any help on this is appreciated. 

The design info is attached.TPS92075 36v 150mA.xlsx

Thanks,

Alex
