ADIsimPower is available at www.analog.com/ADIsimPower
The main difference between most power design tools and ADIsimPower is that all power losses in all external components are calculated with extreme accuracy, this include core losses in inductors, typically only found on some magnetic manufacturers web sites.
ADIsimPower is working with the leading component suppliers (FETs, Caps, Inductors and more) to identify and model the characteristics of these external components in the real operating conditions. Each design is unique and each design has to check millions of operating conditions and limitations in the IC itself and the external components.
ADIsimPower performs every design with optimization in mind, so it select the optimal external components to maximize performance, space and cost based on the entered design parameters. It answers questions like, it is better to use 2x 10uF caps in parallel or a single 22uF cap? This simple question can take even an expert power designer multiple iterations to decide depending on design constraints. Although most power designers would choose the single 22uF cap, often using 2x 10uF caps results in a cheaper and better performing design.
give it a try and you will see how many more simple scenarios like selecting a capacitor can be eased with ADIsimPower.
Good luck and we welcome your feedback

We have added ADIsimPE simulation to some ADIsimPower design tools.
visit www.analog.com/ADIsimPE for more details about the simulator.
A library of circuit examples is included with the new simulator. Also if a tool has the ADIsimPE integration it will allow you to export a simulatable file already set-up to replicate your design.
Jim,
we do not have a simulation tool (SPICE for example) for the ADP1613 that we can distribute to customers.
The limitations of the IC are not necessarily the limitation on how to use the IC. There are always work around options to extend the useful operating conditions of a boost circuit.
For example the addition of Q1 can extend the operating output voltage to a much higher voltage.
Z1 and Rbo also extend the operating input voltage of the application.
This is a good example of how certain ADIsimPower tools allow users to identify solutions not always described in the datasheets.
We test all these configurations and feel very comfortable recommending users to use exactly what the tools recommend without the need for additional simulation.
Best Regards,
LucaV
Hi LucaV,
Thank you very much for your response. Yes, I am very interested in your components. When I tried to use ADP1613 to design a step up DC/DC converter, your datasheet describes that its output is 20V limitation.
But I use ADIsimPOWER, I can get 48VDC output.
My requirements are listed here:
Input: 24VDC
Output: 48VDC
Output current: 0.4A
After I used ADIsimPOWER to get the circuit, I tried to simulate its function, but I couldn’t find any tools.
Best regards
Jim
ADIsimPower is not a simulator, it is a design optimization tool.
What Analog Devices power part are you trying to design? or do you have some specific power requirements?
Let me know your situation and I will point you to the right starting place and procedure.
How to simulate my design by using ADIsimPower.
