This user's guide is intended to demonstrate use of the average Pspice model for the TPS50601A-SP synchronous buck converter. Instructions on importing the unencrypted model netlist into Cadence Pspice® are also provided. The first half of the guide outlines the modeled parameters and specifications and the second half of the guide addresses how to simulate the modeled parameters.

The netlist file (TPS50601A-SP_AVG.LIB) contains the average model of the device TPS50601A-SP. The model incorporates the following parameters:
These parameters are modeled over the full military temperature range, –55°C to 125°C, as well as over the rated Total Ionizing Dose from 0 to 100 krad(Si). Monte Carlo analysis can be performed with the model to include device-to-device variation and changes in supply voltage.
Monte Carlo analysis models device variation for the following parameters:
The default tolerance values are set based on design simulations. The user has flexibility to change these values.
There are two additional variables that need to be set based on the use case:
Environmental parameters like TID and operating temperature can also be adjusted.
The default model parameters are as follows:
