With Vishay reference designs you have a leg up on competitors to efficient create solutions like optimizing energy conversion in EVs

Vishay reference designs help create solutions for challenging issues like EV energy optimization.

Developing electronic and electromechanical systems is a complex process. Basically, it can be divided into three stages: design⇒build⇒test (DBT). Each stage plays an essential role in a successful new product introduction (NPI). However, the design stage is the most critical as it drives and defines the requirements for board manufacturing and PCB design verification.

The foundation of all PCB design processes is the selection of components. Bad decisions here can lead to significant problems downstream that may delay or even halt development. One of the most effective ways of avoiding these types of contingencies is to implement a reference design. And by leveraging Vishay reference designs you can significantly improve the efficiency and reliability of your innovations that require energy optimization; such as electric vehicle or EV design.

Reference Designs: When and Why

Converting an idea into a tangible design is undoubtedly one of the most fulfilling aspects of being a PCB designer or engineer. However, it is often the most frustrating. In fact, the sheer number of options for components and routing schemes can be overwhelming. This coupled with tight development schedules and other objectives; such as maximizing cost-effectiveness, add to the challenges of new product development. A reference design is an effective tool that can help you mitigate some of these issues.

REFERENCE DESIGNS: PROS & CONS
Pros	Cons
Reduce/eliminate common component selection issues	May include unnecessary parts
Significantly reduce/eliminate the need for design validation processes	May require unnecessary space
Reduce time for PCB layout design	Component data and information may not reflect current shortages and trends that may affect production
Ensures accuracy of CAD models and BOM	An existing reference design cannot be patented
Faster development time
Lower development costs than for custom new product design

As shown above, there are distinct advantages when opting to utilize a reference design. Receiving these benefits; however, depends on the source.
