TPS65290LMRHFR

Other Parts Discussed in Thread: TPS65290

Spoke to a TI customer support employee who redirected me here. I am just in need of information on a replacement IC for the PMIC - TPS65290LMRHFR.

Seems impossible to find a replacement. Has TI just stopped making this type of IC altogether?

On another note, seems a bit ridiculous that I can't type in an obsolete part in the part number field for support. It keeps telling me that the part number is not recognised. So unfortunately I am stuck selecting "I don't have a part number", which apparently has a delayed response? Not a great system since I am trying to continue purchasing components from TI. Food for thought..

Thanks

Gene

    Hi Gene,

    Thank you for the replacement part suggestion. We apologize for the inconvenience. The TPS65290 device is obsolete and there is no direct or functionally equivalent replacement for the TPS65290 device. If you can please provide your input/output voltage and current requirements, I will make a recommendation for  replacements in your system.

    Hi Andrew, 

    Thank you for your reply. It is quite a shame to hear that this chip has become obsolete with no direct or equivalent replacement.

    We have designed this component into many of our products and were about to re-manufacture 1000 boards so it's quite disappointing to have received no warning of this item's obsolescence.

    This means we will now have to spend many hours redesigning boards that were just about to head to manufacturer - halting production. This is certain to negatively impact our relationship with the many clients who have orders waiting for our products. 

    Why was there no indication of EOL through email or our supplier (Digikey), or any mention on the TI website? 

    In addition, when searching for "TPS65290", no useful information comes up on the TI website as to what exactly happened to this IC, let alone a datasheet that says it is now obsolete and not to use it in any future designs. 

    If we totally missed this information somehow then please direct us to where I might find it, as well as future EOL/obsolescence updates from TI, as typically we have relied on emails from our supplier.

    Regards,

    Gene

    Hi Andrew,

    I am in the same position as Gene.

    If you could help out in finding a suitable replacement based on the following specs, it would be great:

    We were specifically using the following features based on a system using a Li-Ion battery

    1. The V_MICRO output to power our micro-controller
    2. The 2 x Buck/Boost outputs to power two of our communication modules
    3. 1 of the LDO outputs to power our analogue circuitry
    4. We could configure the internal switches to turn these outputs on/off
    5. This could all be configured at runtime using SPI from our micro-controller.

    At a minimum, I require a buck/boost PMIC as we are driving 1 x 3.3V rail and 1 x (3.3V - 5V) rail, from a Li-Ion battery (ie 3.5V – 4.2V)

    Like to have, a buck/boost PMIC to drive 2 x 3.3V rails and 2 x (3.3V - 5V) variable rails, from a Li-Ion battery (ie 3.5V – 4.2V). Controllable with a miro-controller interface.

    Hi Gene and Craig,

    I will follow up with you directly via email to discuss the topic. I am going to close the thread for now.
