STMicroelectronics has linked its eDesignSuite with the web-based Smart Transformer Selector
published by Wurth Elektronik to overcome challenges related to ordering custom parts and saving
bill-of-materials (BOM) costs and turnaround time.


are online design tools that generate the transformer specification, but they
leave designers to figure out the best way to satisfy specs, often by ordering
a custom component. And that adds to cost and turnaround time.

collaboration will enable power-supply designers to automate selection of a
suitable off-the-shelf transformer while still working in the eDesignSuite online
environment. That, in turn, will allow engineers to complete system designs for switch-mode power supplies (SMPSes),
LED lighting, filters, and motor drives quickly
and cost-effectively.

to Alessandro Cremonesi, group vice president of Central Labs at STMicro, the new feature introduced in eDesignSuite
facilitates the final part of the power design process. “It enables engineers to get a prototype up and running
on the bench in a couple of days instead of waiting several days or weeks to
procure a custom transformer.”

Huumala, product marketing and development manager at Wurth Elektronik, added
that Smart Transformer Selector (STS)
helps designers search the company’s portfolio to find the right transformer
quickly and efficiently. “Bringing STS together with ST’s eDesignSuite enables
our mutual customers to complete their bill of materials with transformers that
have already been designed, tested, and released for production.”
