Choosing Power Integrations IC with PI Expert
Choosing the Right Power Integrations IC for Your Design
When starting a new design, selecting the right power integrations IC can be a daunting task. With numerous options available, it's essential to choose an IC that meets your application requirements and specifications. In this article, we will guide you through the process of selecting the ideal Power Integrations (PI) IC for your design using the PI expert tool.
|
Understanding the Importance of Application Selection
The application selection is a crucial step in choosing the right PI IC. It enables the PI expert tool to start with design defaults and specifications that would otherwise not be known to the tool. This helps you get started with your design sooner.
|
Using the Product Filter to Narrow Down Options
The product filter is a powerful tool that allows you to capture the necessary specifications for your power supply design. You can input parameters such as output power, input types, number of outputs, and more.
|
Output Power Selection
In this example, we will select an output power range of 40 to 100 watts. This range allows us to design a power supply that can handle various load requirements.
|
Input Type Selection
We will choose the universal input type, allowing our power supply to work anywhere in the world. This is particularly useful for designs that need to accommodate different voltage and frequency requirements.
|
Number of Outputs Selection
In this example, we will select a single output. However, the PI expert tool allows you to design power supplies with multiple outputs if required.
|
Isolated Supply Selection
We will choose an isolated supply, which is essential for designs that require electrical isolation between the input and output stages.
|
Output Type Selection
In this example, we will select a constant voltage and constant current output type. This allows us to design a power supply that can provide both constant voltage and constant current outputs.
|
Topology Selection
We will choose the flyback topology, which is a popular choice for designs that require high efficiency and reliability.
|
Narrowing Down Options with the Product Filter
After filling in all the inputs from the product filter, you can see that the number of parts remaining has decreased. In this case, only four options are available.
|
Selecting the Ideal IC
If you know which part you want to use, you can select it directly from the remaining options. Alternatively, if you're still unsure, you can click the "Help Me Choose" button to bring up the device recommendation wizard.
|
Using the Device Recommendation Wizard
The device recommendation wizard helps narrow down the possible ICs that can be used for your application. In this case, PI expert recommends just two parts and provides detailed information on why one part can be prioritized over the other.
|
Launching Your Design
Once you've selected the ideal IC, you can launch into your design using either PI expert (GUI-based) or PI XLS (spreadsheet-based). Both platforms provide a comprehensive design environment for creating and simulating your power supply design.
|
Conclusion
Selecting the right Power Integrations IC is crucial for any power supply design. By using the PI expert tool and following the steps outlined in this article, you can ensure that you choose an IC that meets your application requirements and specifications. Whether you're a seasoned designer or just starting out, the PI expert tool provides a powerful platform for creating efficient and reliable power supply designs.

| Power Design |
| Definition: |
Power design refers to the process of creating a visual representation of data, information or knowledge to communicate insights and support decision-making. It involves the use of various elements such as charts, graphs, maps, and other visualization tools to present complex data in a clear and concise manner. |
| Background: |
The concept of power design emerged from the field of information visualization, which has its roots in the 1960s. However, it wasn't until the 1990s that the term "power design" started gaining popularity, particularly with the rise of business intelligence and data analytics. |
| Key Principles: |
Effective power design relies on several key principles, including simplicity, clarity, and precision. The goal is to create visualizations that are easy to understand, yet powerful in their ability to convey complex insights. |
| Applications: |
Power design has a wide range of applications across various industries, including business, finance, healthcare, and education. It is used to support decision-making, identify trends and patterns, and communicate insights to stakeholders. |
| Tools and Techniques: |
Power design utilizes a variety of tools and techniques, including data visualization software, such as Tableau, Power BI, and D3.js. Other techniques include the use of color theory, typography, and storytelling to create engaging and effective visualizations. |
