Part Number: TPS548D22
Other Parts Discussed in Thread: TPS548B22

Hi Expert,

The engineer would like to design the TPS548B22 and TPS548D22 into the same PCB for flexibility.

Can you advice how to proceed the NC Pin 6,7,26,27 of TPS548B22 .

Thanks

Best regards,

Eric Lai

    You can connect the NC pins of the TPS548B22 to the same nets they are connected to on the TPS548D22 

    Pin 1, 2, and 3 are not used and can be connected to the Exposed Pad (GND)

    Pin 6, 7 are not connected, but can be connected to the SW net for layout compatibility.

    Pin 26 is not connected, but can be connected to the PVIN net for layout compatibility.

     Pin 27 is not connected on either the TPS548B22 or TPS548D22 and should be connected to the Exposed Pad (GND)
