Hi TI master
TPS53679 datssheet Figure 7-1 has defined the power on sequencer: it is 5V is power up before 12V.
But reference design schematics PMP20489 参考设计 | 德州仪器 TI.com.cn: CSD95490+TPS53679, we must get Vin 12V ,and then can get 5V from VRM output, so the power seqencer is 5V power up after 12V.
Now,we are confused and worried that if it can get CSD95490 at risk or not ,
Question is : if we use reference design , 5V can power up after 12V or not ?
Thanks!
