According to TPS65910Ax User's Guide For AM335x,the VDDSHVx delays 2000uS after VDDS_DDR.In our design,the power supply of VDDSHVx is 3.3 V , and in PCB the power 3.3 V is source from DC/DC module output that is controlled by the VDDS_DDR.Now the delay time is 1500 us.TRM does not give a relevant min value.Do this design have a problem?
