STM32H757IIT6 SMPS Problem

[FWANG.1]

Hi ,

I use STM32H757IIT6 now ,but follow the STM32H757XI EVB's Power design.

Use SMPS diretly supply model for Vcore.

But when power up the system,the total current up to 500mA,and the CPU chip is very hot.

I attach the sch ,and could you help me for it ,why the chip over current?

Thanks!
