TINA/Spice/TPS62163: Inverting circuit model

Part Number: TPS62163
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hi,

Customers are trying to make inverting circuits using TPS62163.
Customers are considering circuits like the following materials.

Http://www.tij.co.jp/jp/lit/an/slva469c/slva469c.pdf


Can I simulate the inverting output (3.3 V -> -5 V / 60 mA) of the TPS6216x series with TINA simulation tool?
If yes, is there an inverting circuit model?

Best Regards,

Yuto Sakai

    Hi Yuto Sakai,

    The existing TPS62163 model does not support an inverting configuration. The following FAQ gives gives some more information about this.

    Hi Lakshmi-san,

    Thank you for your reply. 

    I changed the TPS62163 transient model (slvma51) and designed a circuit like the attached TSC file.

    TPS62163_inverting.TSC


    As a result of simulation with this circuit, it looks like the following image.


    As you can see from the FAQ, I understand that about 0 V is output because all the GND nodes of the spice model are internally connected to 0 V, is this correct?

    Also, are there any plans for TPS62163 to support inverting configuration?

    If No, would you make this device available with simulation of inverting  circuit?

    Best Regards,

    Yuto Sakai
