Power trends

Power density

More power, less board space. In addition to being a trend in applications across all markets, it is also one of the key benefits of using a step-down module. Buck modules feature an integrated inductor and FETs to not only minimize power supply size, but also simplify design and help get customers to market faster. On the inside, the centerpiece of each module is a high-efficiency buck regulator surrounded by a layout optimized for thermal performance.  

High-density power modules are a great choice for powering high-current digital loads like FPGAs and processors. Use our processor-attach tool to find the best power supply devices to surround your FPGA or processor.

Low EMI

Mitigating power-supply EMI can be a major challenge for many power-supply designers, so why not make it as simple as possible? With a high level of integration and an internal layout optimized to minimize noise, buck modules are an excellent choice to save design time and help you comply with difficult standards like CISPR 22 Class-B. Take a look below at some of our latest and best DC/DC step-down modules for EMI performance.
