LP87332D-Q1 and LP873220-Q1. all the output voltage was normal and we follow power on sequence.
But we fine the EN_TPS51200 (LP873220_GPO2) and SW_3V3 (LP87332D_GPO), PORz
(LP87332D_GPO2), (LP873220_GPO), and also PGOOD was the same 0V.
what`s happen the GPIO? it`s look like setting mode selections?
If any suggestion, Please advise me.
