TPS51285B: CSD87335Q3D

Part Number: TPS51285B
Other Parts Discussed in Thread: CSD87335Q3D, , CSD87330Q3D, CSD87351Q5D

Hi,

We have 5V/24A application, does power block CSD87335Q3D is suitable for TPS51285B 5V output?

We have used CSD87330Q3D(20A cons.) is proviuos project, but now need support to higher output current.

Thanks!

Jeff

  • Hi Jeff,

    TPS51285B can drive the CSD87335Q3D (25A).

    But the 25A MOSFET maybe not be used in a load with Iout(MAX)=24A. You can ask the customer to confirm the inductor current ripple and OC value in Iout(MAX)=24A application, then decide if the 25A MOSFET is enough.

    Best regards,

  • Hi Harry,

    if consider inductor current ripple and OC value may over 25V, CSD87351Q5D is more suitable to get more buffer, right?

    Thanks!

  • Hi Jeff,

    Yes, CSD87351Q5D (32A) is more suitable, has the buffer enough. But it is best to confirm parameters such as inductor current ripple and OC value with the customer.

    Best regards,
