UCC2897A: Short circuit protection issue

Hello TI team, we are using UCC2897A IC. The IC is creating problem during output short circuit. In my design, the separate regulated supply is connected to the IC which create problems in short circuit conditions as the pulse by pulse current limiting prevents the device from hitting the shutdown overcurrent limit and going into hiccup mode and the voltage to the chip not drop out. In short-circuit condition, the IC maintains its PWM at lower duty cycle with output voltage drop to constant 2V and output current 65A. While my normal operation output is 14V/35A load.
