Hi Akshat,
HI,
We are connecting PGOOD of one TPS548A20 to enable of other TPS548A20
We are connecting PG of TPS548A20 regulator to other TPS548A20 Enable pin.
We are using 12V pull-up for the enable pin. we are using resistor divider on this 12V supply to make it to 3.3V.
This 12V_BUS2 will be first supply to turn on. The schematic is shown below.
Can you please let us know if this configuration is fine.
Thanks,
Ramya
