Other Parts Discussed in Thread: TPS54227,
Hi team,
Currently customer’s TPS54228DR is facing shortage problem and they want to replace it with TPS54227DDAR. As you mentioned, the difference is that TPS54227DDAR has thermal pad.
- Is the thermal pad be internally connected to GND pin?
- If customer don’t want to change the PCB, can the thermal pad of TPS54227DDAR be left float?
- If we keep the thermal pad of TPS54227DDAR float, will its power dissipation ability the same as TPS54228DR?
Thanks!
