Other Parts Discussed in Thread: TPS61220, LMR61428, TPS61030, TPS60150

Hi,

 I need a micropower dc/dc converter (from 3.0Vdc to 5.0Vdc max current 50 or 100mA) for a new design.

Not able to find the product selector after the latest website update.

Any suggestion for a P/N and/or a link to the selection page?

    I think right now the Webench front end has the most comprehensive component selection.  Your next best option is Power Quick Search.  Are you looking for Vin = 3 V, Vout = 5 V at 100 mA?  Let me know.

    Thanks John,

    And yes, I am looking for Vin=3v, Vout=5V at 100mA.

    It is for a pressure sensor, so needs to be clean.

    What is your suggested part?

    None of the devices I directly support will meet that spec (you will need a boost converter).  I'll take a look and see if anything suggests itself.

    power quick search returns 39 options for charge pumps and dc/dc switching converters.  More option if you want a controller w/ external FETs or a module.  I would probably go with a converter or charge pump.  So it will depend on your other care abouts...(size, cost, efficiency, etc).

    John,

    I need to do some comparison study between the charge pump (tps60150)

    and switch boost (tps 61222) and pick one of them.

    Thanks again.
