• Cost: Balancing performance with cost-effectiveness is crucial for mass production. Designers must consider the trade-offs between using higher-quality components that may increase the overall cost and achieving the desired performance standards within budget constraints.

Moreover, the choice of components—such as inductors, capacitors, and switches—can significantly impact the converter's performance, efficiency, and size. Selecting the right components requires a deep understanding of their characteristics and how they interact within the circuit. Additionally, the layout of the printed circuit board (PCB) plays a vital role in the performance of a DC-DC converter, as it can affect electromagnetic interference (EMI) and overall efficiency. Engineers must apply best practices in PCB design, including minimizing loop areas and maintaining proper grounding techniques.
