Understanding IC Equivalents and Why They Matter When designing a printed circuit board (PCB), one important consideration is selecting the right integrated circuits (ICs) for your application. In many cases, you may find that the specific IC you initially planned to use is unavailable, obsolete, or too expensive. This is […]

Understanding Power Converters Power converters are circuits that transform electrical energy from one form to another. In the context of power supplies, converters typically step down a higher DC voltage to a lower DC voltage required by the load. Converters can be further classified into different types based on their […]
