Conclusion

The rapid growth of electronics has put tremendous strain on the design of power converters, where complex systems are crammed into ever-smaller spaces. The close proximity of sensitive systems makes it challenging to suppress EMI. You must take extreme care when designing power converters to comply with the limits set forth by standards bodies to ensure that critical systems can operate safely in a noisy environment.

Designing for low EMI can save you significant development cycle time while also reducing board area and solution cost. TI offers multiple features and technologies to mitigate EMI such as spread spectrum, active EMI filtering, cancellation windings, package innovations, integrated input bypass capacitors, and true slew-rate control methodologies.

Employing a combination of techniques with TI’s EMI-optimized power-management devices ensures that designs using TI components will pass industry standards without much rework. TI products enable you to remain under end-equipment EMI limits without sacrificing power density or efficiency.

To learn more about TI products that use these technologies, including buck-boost and inverting regulators, isolated bias supplies, multichannel integrated circuits (PMIC), step-down (buck) regulators and step-up (boost) regulators, see ti.com/lowemi.
