Boost LED Driver

We are using LED6001 LED Driver in a Flasher.

The problem is when the input is less than 10.5V it works O.K but when the input is more than 10.5V the LED current reduces to almost 10mA or shuts down. The Problem is same with 6LEDs at the O/P and 12LEDs at the O/P. We have also tried shifting the OVP much above the O/P required volatage, but still this problem exists.

Please help us to resolve the problem.

 Please find the updated schematic.

I think the problem is with Input current sensing and COMP R-C values, could anyone help me to sort out it.
