In my design iam using Viper25DTH.
My o/p power is upto 6W i.e. 4.1V@1.5A.

But whenevr i am ging 1W load, the voltage on VDD pin starts to oscillate between 4.5V to 15V and feedback voltage is upto 3.4v, it seems that OLP protection is on at this stage.

I have selected Rlimt=18K
I  have done many iterations to achieve o/p but invain.
Please suggest
