LM5069: The board tries to power up, and then LM5069 gets burned

Part Number: LM5069

I am using excellent FET, PB031NE7N3 - which is only 6mohm at 175C at full 100A current.

48V, 3mohm sense resistor (18A limit).  RPWR=40.2K, CTMR=100nF (0.1uF).  Output Capacitance=132uF.  I have 500mA of constant load at power up.  My UNDER/OVER are correct.  I have no diode protection at load

But, when I power up, LM5069 tries to turn on Gate (in pulses) and eventually burns out

What am I doing wrong?
