ADP1071-1 evaluation board not working

Hi i am testing the evaluation board of ADP1071-1 for the first time.

I am not getting proper output voltages at any laod condition.

The Vreg1 is showing around 9V and gate pulses are coming when i turned on 24V.

The pulse width of gate pulse is only 200ns and switching frequency is around 48.5kHz.

i checked with full laod and no load condition the gate pulse is not changing. the output voltages are coming very  very low

The peak current limit is hitting in the soft start period only . the output diodes are replaced with new diodes but still same condition

given external 5V in the output sideVVD2 but same result .

What could be the reason for this behavior.
