TPS53647 heatsink

Other Parts Discussed in Thread: TPS40428, TPS544C20, TPS53647

As you know, there is some heatsink on the TPS53647, TPS544C20 and TPS40428 on our design,

do you have any data about how much force the TI parts can endure when the heatsink is attached?   Thanks

  • Hi Mick,

    The TPS53647 and TPS40428 do not need heatsinks since there are not any power FETs or similar components located on chip. Since TPS544C20 is an integrated FET part it may need heatsinking depending on the application.

    I've reach out to that product line to get their recommendations on proper heatsink attachment for you.

    Thanks,

    Carmen
