This user's guide is intended to define the Worst Case Analysis (WCA) PSpice model for the TPS7H5001-SP. Instructions on setting up the unencrypted model for simulationSIMPLIS® are also provided. The first section of the guide outlines the model parameters and development. The second section covers different options for setting the model up to run simulations. Finally, the third section addresses how to run different types of simulations.

The TPS7H5001-SP WCA model takes the TPS7H5001-SP SIMPLIS Model and allows users to edit specific parameters related to the frequency response of a power converter. Monte Carlo analysis can also be performed to observe the distribution of behavior across a specified sample size of devices. The following tests/device characteristics have provided data in order to find worst case conditions for parameters associated with frequency response analysis.
Data characteristics provided comes from an internal statistical model of variation due to the manufactering process.
Data characteristics provided after devices exposed up to the maximum rated Total Ionizing Dose (TID) of the device: 100 krad at a does rate of 0.01 rads(Si)/s
Data characteristics provided at 25°C after 1,000 hours of testing at 125°C, and meant to emulate 15 years operating at 65-95°C as defined by Group C specifications in MIL-PRF-38535. Additional data provided at -55°C and 125°C for the same devices.
In the model, the specific device parameters influenced by the above variation include:
