TPS65263-Q1: As I was trying to stimulate this part in TINA software and I found TSM file regarding this, but pin configuration is not similar as the PMIC IC we using in our schematic

Hi, SAJAL 

The model just includes the necessary pins for transient simulation and Bode plot simulation, it doesn't include I2C function and not include Rosc pin too. 

So the symbol of model is different with actual device's Pinout.
