For designing flyback converters using STMicroelectronics' VIPer series ICs, the primary software tool is the ST eDesignSuite
Would you like a step-by-step guide to using eDesignSuite for a VIPer flyback design instead?
With support for flyback, buck, and buck‑boost topologies in both isolated and non‑isolated configurations, VIPer ICs are suitable for everything from small appliance power supplies to industrial auxiliary converters. Whether you need a 4 W, 12 V supply for a smart meter or a 15 V/1.2 A isolated power stage for a home appliance, there is a VIPer device tailored to your requirements.

Adjust core materials (e.g., 3C90 or N87) and define maximum flux density ( Bmaxcap B sub max end-sub ) to stay safely below saturation limits (
The demand for high-efficiency, compact power supplies has made STMicroelectronics’ VIPer series a staple for engineers. However, moving from a datasheet to a working prototype requires precision. If you are searching for options to build a better , more reliable power supply, this guide covers the essential tools and the "secret sauce" for optimizing your design. Why Use Dedicated Design Software?
In the rapidly evolving landscape of power electronics, efficiency and reliability are paramount. Among the various topologies used in modern Switched-Mode Power Supplies (SMPS), the flyback converter remains a dominant choice for low-to-medium power applications due to its simplicity and cost-effectiveness. However, the theoretical simplicity of a flyback converter belies the complex mathematics required to optimize its performance. This is where specialized tools, such as the VIPER flyback converter design software, become indispensable. Accessing and utilizing the "better" or latest version of this software is not merely a matter of convenience; it is a critical step in ensuring robust magnetic design, thermal management, and regulatory compliance. Define voltage and maximum current requirements for all

Most VIPer ICs feature built-in frequency jittering to spread electromagnetic interference (EMI) energy across a broader spectrum. The design software accurately calculates the required input differential and common-mode filter values based on this jitter profile, reducing the physical footprint of line filters.
