LP3925: Input and Output voltage range of all Buck regulators and LDOs in LP3925 and register mapping details

Part Number: LP3925

I am unable to find input and output voltage range of all buck regulators and LDOs present in LP3925.

Buck1-3    

LDO1-10

WLDO1-3

Also I don't find any register mapping details for programming in the datasheet.

Request you to provide the details so that I can evaluate how best it meets my design requirements.

Regards,

Kiran

  • Hi Kiran,

    I have assigned your request to concerned Applications Engineer and we will get back to you as soon as possible. Please note that this is vacation time in US and there may be some delay in answering your question.

  • Kiran,
    Referring to an earlier response to a previous question.

    The information you are requesting is not available.

    I realize that you have some time reviewing and potentially designing in this IC. The bad news is that this part is not recommended for new designs. At this time TI is not supporting the LP3925.
    We do have many newer IC that would be a great fit for your application. Please contact your local FAE to find a proper replacement for this part.

    Sincerely,

    Gordon Varney

    Gordon,

    Thank you for informing about NRND status of LP3925. TI website doesn't mention anything about it and hence I had gone ahead in shortlisting this device.

    Can you recommend any equivalent new part for LP3925? I am also looking into LP3974 and working with local TI sales office towards getting an NDA signed and get access to complete datasheet. I hope this is also not having NRND status.

    Regards,
    Kiran

    Kiran,
    The LP3974 has not been confirmed NRND, but it does not look good for long term. The industry is moving away from system PMIC's to processor specific PMIC's.

    Take a look at the TPS65912. The main difference is that it does not have the integrated charger. This part should be more cost effective as well.

    If you can provide a power requirements breakdown and a feature list, I can look for a better fit for you. Feel free to go through your local TI FAE, as he can address your issues directly with our PMIC team.

    Sincerely,

    Gordon Varney
