TPS548A20: Regarding Power Good of TPS548A20

Part Number: TPS548A20

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
