TPS7A24: TPS7A2450 Simulation model

Part Number: TPS7A24

Dear Sir/Ms.

I have to download the TPA7A24XX PSPICE from the Ti website, but the default value is TPS7A2401. We did it a bit. There is no TPS7A2450. How can I change it to TPS7A2450? Or do you have a TPS7A2450 model?


Thank you

Kami Huang

    Hi Kami,

    There is only one model for the TPS7A24.  If the design uses a fixed voltage version, you can simply use high value resistors to set the setpoint as all that changes is the gain of the internal error amplifier.  The internal resistors are trimmed to give 5V very precisely, so we can enter untraditional resistor values into the model and this is okay.  Use the top setpoint resistor as 1.5Meg and the bottom setpoint resistor as 494.7k.  This should produce 5V.  You will also need to set up auto converge - see the settings I used below.  Don't forget to update your input voltage.

    Thanks,
