TPS65988: TIDA-01515 modifcations

Part Number: TPS65988
Other Parts Discussed in Thread: TPS563200, BQ25703A

Hi, I am working with a customer interested in the TIDA-01515. The reference design specifies the max output power of 45W. Can this be modified to support 60W output power? If so, can you please provide input on how to modify the design?

Thank you,

Ishraq

    Hi Ishraq,

    Yes, this design can be modified to support 60W. The Source capabilities can be changes from 20V/2.25A to 20V/3A by using the TPS6598x Application Customization Tool. However, the batteries selected must be able to support 60W output as well.

    Thanks,
    Eric

    Hi Eric,

    This may be a something I'm over looking or a misunderstanding of the TPS65988, but:

    How does the TIDA-01515 source 20V at 2.25A (or 3A if reconfigured) if the TPS563200 can only output up to 7V. Is there a boost occurring on the TPS65988 that I'm not seeing?

    Can this reference design only source 5V at 3A? If so, do we need to find an alternative device to the TPS563200 to supply 5V, 9V, 12V, 20V?

    Thanks,
    Nick

    Nevermind, I answered my own question.

    The BQ25703A is a buck-boost battery charger which can handle all output voltages needed by the USB PD standard. The buck/boost conversion happens there. The TPS563200 is only for PP_HV2 which is the BC1.2 compliant port.
