Other Parts Discussed in Thread: TPS650861, TPS53647, TPS548D22, TPS54618, TPS53515, TPS54418, TPS65251, TPS65262-2

Hello,

Customer is looking for referenced PMIC for Arria 10 GX320.

Does TI have reference PMIC? Only can find below post.

Please let me get Reference Power design for Arria 10 GX320.

Regards, 

Nicky

    Hi Nicky,

    [2020 Edit: The TPS650861 is the user programmable version of TPS650860 which can be programmed for a wide variety of cases and is an excellent option for FPGA attach with a wide variety of current]

    We don't have a PMIC reference design for the Arria 10 family. There is a very wide range of use cases and no single solution tends to work for multiple opportunities. The most promising was the use of the TPS650860 with an MSP430 to set the voltages during boot and then enable rails by I2C. Rail mapping will vary based on how much current is desired from each.

    If you have any power tree we can help to identify if there is a good PMIC fit.

    Hi Kevin,

    If there is no PMIC solution, customer wants to use attached TI Switching Regulator Power Proposal. (see attached.)

    But those  parts are too heavy to use customer's solution, so she wants to get new proposal as below table.

    Could you recommend a little light solutions?

    Hi Nicky,

    Webench can probably create a discrete solution for you. For PMICs, the TPS65262-2 could supply up to 5 rails, though if used for VCCA_PLL, it would be a bit short of current. Otherwise, the TPS65251 removes the LDOs and provides a bit more current for the bucks.
