TPS61097 - other voltage versions?

Other Parts Discussed in Thread: TPS61097-33

TI Folks,

    What is the story behind the alternate voltages versions of the TPS61097-33, in

particular the adjustable and 2.7V?  This regulator has come up on our radar several

times over the past year or so specifically due to its spectacularly low shutdown

current and support of bypass.  Mention of other versions has been stripped from the

data sheet which seems odd given the statement here other versions are in development.

Could you provide some concrete information on status and presumed availability?

Thanks,

  • Since this is a question specifically about the TPS61097 devices and not powering the MPS430 with a coin cell, I split this post and made a new thread.

    Dick should reply, but I'm sure he would like to know your voltage needs, volumes, and schedule for any other voltage versions.

  • Note creating a new post loses the informative context in which it was originally written.

    Namely the indication here by (AFAICT) TI of other voltage option versions being in

    development.  This seems odd seeing as the mention of these prospective

    versions has been removed from the datasheet.  So a customer is left

    wondering what's going on from a product roadmap perspective.  Particularly given

    the above reply which essentially is asking for marketing justification for

    these versions.  In short, are the alternate voltage versions real products

    on the roadmap with a sustainable customer base?  We wouldn't want

    to rely on a device with suspect market traction.

    In terms of voltage needs, it seems downright mystifying an adjustable

    voltage version of the TPS61097 isn't already available as that would

    cover the full design range, with specific fixed voltage versions introduced

    if/when market volume unfolds.  In terms of our schedule we're on

    the fence with the 3.3V version in terms of designing it in as an alternate

    to Microchip and Maxim devices, on the weak assumption an adjustable

    voltage version will surface.  Otherwise for example, wrapping two

    inexpensive mosfets around an MCP1624 addresses our bypass voltage

    drop and shutdown current goals, in a less expensive solution albeit at

    the cost of some board space.

  • Does the lack of a concrete response imply to your customers the TPS61097 in other than the 3.3V version has been abandoned as a product?

  • Mike,

    We are working on a schedule for all versions.  The next release will be for the 3.0V version, but I do not have a firm date yet.  Other versions will follow.

    Regards,

    Dick
