WEBENCH-POWER-DESIGNER: Thermal simulation to be added to new HMTL webench?

Part Number: WEBENCH-POWER-DESIGNER
Other Parts Discussed in Thread: TPS61087

Team,

I saw the below answer:

https://e2e.ti.com/support/tools/sim-hw-system-design/f/234/t/769713

Do you have a timeline when the feature will be added?
Will it be comparable to what is shown in video “1.2 Thermal Design Made Simple" at https://training.ti.com/thermal-design-made-simple?cu=1135313

Thanks in advance,

A.

    Hi AnBer,
    We decided not to add the feature that does thermal simulations. Instead we have calculations that will alert the user if the temperature of any of the power components exceeds the limits for the component. This is called the "Thermal alert" feature and this is already released.

    Regards,

    Hi Gerold,

    Thanks for the feedback.

    I personally liked the Thermal simulation of the older webench, especially since the online training (that was showing the calculation vs Webench simulation) made it clear to customer on the benefits:
    training.ti.com/managing-heat-dissipation-dcdc-switching-regulators

    For the new webench (HMTL5) It is not clear today on what formula/calculation the Alert is based on. As shown for the TPS61087 use case (see the off-line email we exchange) the Alert does not give explanation on why/what you need to pay attention to.

    We probably do not need a precise simulation (like showing temperature of the different point of the PCB).
    But it would make sense to still give a simplified summary table that gives high level information (giving the max temperature of the die for the given parameters, the power dissipation in the TI device).
    I hope you will consider it in the future.

    Thanks,
    A.

    Hi AnBer,
    The new WEBENCH (HTML5) will still give temperature of the various key power components in your design. You can look at the table called "Operating Values" below the schematic and this would give the Tj information for the IC, MOSFET (if external) etc.
