TPS65130: Spice models missing, including for TPS65131

Part Number: TPS65130
Other Parts Discussed in Thread: PSPICE-FOR-TI, TPS65135, , TPS65133

I'm trying to design a split-rail dc/dc converter for measurement system.  These parts fit my needs best due to low PCB area.  However support in Webench is limited (to only one of the rails) and has the disclaimer to validate designs with SPICE.  However there are no spice models in PSPICE-FOR-TI or TINA.   I prefer TINA because its fast and much more likely to run to completion while PSPICE-FOR-TI seems to always be slow with so many convergence problems that I often have to give up on it.  The other issue is that the semiconductor shortage means that I'm never sure if a part is available even for a small run of prototypes, so I need SPICE models for other power supply parts to create backup designs, which often don't have them either.

    Hello Eric,

    Unfortunately, we do not have spice/TINA models available for this older device. If you would like, you can make a schematics based on the typical application schematics shown in the datasheet and I will be happy to review it to ensure that there are no issues with the design.

    Kind Regards,

    Thank you.  It's difficult to tell which devices are older or newer!  Can you offer an approach to part selection that reduces the obstacles to creating verifiable designs?  Can you recommend a part that will provide similar functionality and be better supported for verification of designs?

    Hello,

    For split rail (+/- output voltages), we only have TPS65130/131, TPS65133, tps65135 but simulation models are not available for these devices.

    Datasheets do have all the information, including typical application schematics, to make a successful design but they do not offer a simulation model.

    Kind Regards,
