The chip design under negative pressure keeps burning the chip

Part Number: LMR33630
Other Parts Discussed in Thread: MC34063A

Tool/software:

、The chip design under negative pressure kept burning out the chips. There were a total of 5 pieces and they all burned out.

Positive voltage is fine, but negative voltage output is not. Please check if there is any problem with this design



Also, for a negative pressure output solution similar to MC34063A, which aims to achieve a frequency of 150KHZ, are there any suitable recommendations?
