Power IC Model Library

AEi Systems announces the
Power IC Model Library for PSpice® and OrCAD® — Now Version 4.5!

Available now for US$1995.00 + $495 1st Year's Maintenace
Model lists: PDF Excel

Over 1700 high-fidelity models, including dozens of hyper-accurate cycle-by-cycle transient models, all in one convenient place.

A Major Breakthrough

Modern SMPS applications demand higher switching frequencies, greater efficiency, and lower standby current. Traditional state-space models often miss nonlinear factors critical to performance.

Our models accurately capture nonlinear effects such as propagation delay, switching speed, drive capability, maximum duty cycle/current limits, and startup phenomena. Compare components from different vendors and analyze implementations like peak current mode control, hysteretic current control, and low voltage/current operation.

Using analog behavioral functions, our models greatly reduce simulation runtime—most simulations complete in minutes. In many case, both average and transient models are available.

Example application circuits are included for most IC models. OrCAD Capture symbols and test schematics are provided.

Why Choose Models from AEi Systems?

Many models from vendor sites or EDA packages lack quality and fidelity. They may not be validated against test data or datasheets, and often miss key characteristics designers expect. AEi Systems maintains a much higher standard for model accuracy, documentation, and support.

Hard-to-Find Power IC Models

Vendors represented include Texas Instruments, Renesas, International Rectifier, Analog Devices, Vishay, Power Integrations, Microchip, and ON Semiconductor. Models cover PWM controllers, switching regulators, multi-phase controllers, PFCs, integrated switch & boost controllers, hysteretic controllers, IC regulators, FET drivers, opto-couplers, and more.

Requirements to run the models

  • OrCAD Capture/PSpice version 15.9 or greater
  • MicroSim Schematics version 8.0
Older/newer OrCAD Capture versions should run the models. Some newer models (TI, etc.) are encrypted and require OrCAD Capture 15.9+.

Maintenance support is recommended as the models will be updated and the libraries augmented in the future. Requests for new models are gladly accepted.

Other SPICE Programs

Most models use standard PSpice constructs and may run in other PSpice-compatible simulators. AEi Systems supports conversion to other syntaxes on request.

Models can be translated to other SPICE flavors for a nominal charge. The simulator must support If-Then-Else and other behavioral constructs.

Important Note:
Most Texas Instruments models require OrCAD/PSpice 9.2+.

Frequently Asked Questions

If you are not able to find the answer you need, or just have a unique question.
You can email us at info@aeng.com or call +1-702-625-0568 and a qualified engineer will help with your question.

Q. Are Models avialable in other syntaxes (LTspice, QSPICE, Simplis, etc.)?
A. Yes. All of the models are available for translation. There is a cost for such a translation and we are happy to quote it. While some simulators can read in PSpice syntax (not the encrypted models), it is not guaranteed that the model will run correctly. As part of the translation process we test the model in the target simulator and provide the test circuit as part of the deliverable.

Q. How can I evaluate the models in the library?
A. You can evaluate the performance of various models by reviewing one or more of the documents above. If you have questions about a specific model's performance, please contact us directly with your question. It may be possible to provide a model to test.

Q. How are the models tested?
A. Each model in the Power IC library is tested under various conditions using multiple test circuits for specific functions and then again in one or more full application test circuits. The results are compared to data sheet performance and in most cases actual bench measurements.

Q. What features do the transient IC models have?
A. The Power IC Library models are normally pin-for-pin compatible with the actual physical part. All key functions of the actual chip are modeled with the exception of variations with temperature. Nonlinear characteristics such as propagation delay, switching speed, drive capability and maximum duty cycle/current limits, startup phenomena are included and based on data provided by the manufacturer.

AEi Systems strives to produce models that meet all key performance metrics and exhibit “typical” performance as specified in the data sheet or performance that is within given Max-Min specifications. Smoke alarm parameters are not currently implemented.

Q. What types of simulations can I run?
A. The transient models can be used in all types of simulations including startup, line transient, load transient, and steady state, provided that the external circuit and stimulus are properly adjusted. AC stability/frequency response simulations are also possible with the state space models provided. Often state space average models can be used in startup simulations as well.

Q. Can I share the models with other engineers?
A. ABSOLUTELY NOT. The license allows you to use the models with one and only one copy of PSpice. If the models are being used with multiple copies of PSpice, then one copy of the library must be purchased for each copy of PSpice.

The model libraries have special tracking codes in them so that any unauthorized sharing or distribution can be tracked back to the purchaser. Copying or distributing the models is STRICTLY prohibited and those who violate the law will be prosecuted to its fullest extent.

AEi Systems has spent many man-years developing these models. They should be thought of as software and intellectual property in every sense. Users are not allowed to distribute, post, transfer, resell, or repackage the models or any derivatives of the models.

Q. Can I use the models with other SPICE simulators?
A. Yes. If you are trying to use the models with other SPICE based simulators you will have to make sure that the simulator supports the PSpice E/G element's If-Then-Else syntax. If you need one or more of the models translated to another SPICE syntax (LTspice, HSPICE, etc.) please contact AEi Systems.

Q. How fast do the transient simulations normally take?
A. The time it takes to run a switch mode power supply simulation is directly related to a number of factors:

  • Your computer's performance
  • Complexity of the model and external circuitry
  • Length of the simulation
  • Time step of the simulator

The last item is driven by a number of factors including the stimulus and loading, soft-start and compensation components, the simulator .OPTION tolerances, the TMAX timestep setting, and the overall frequency content of the circuit (edge speeds).

It is not uncommon for SMPS simulations to take 15-30 minutes each. However, most of the example simulations run in just a few minutes. With proper setting of initial conditions and tolerances, simulation runtimes should be very reasonable given today's computer performance.
