3.3 Other EMI Mitigation Techniques

There are many more proposed solutions to mitigate EMI besides the spread spectrum technique. Some of the techniques available to help reduce EMI emissions in SMPS are by implementing additional input filter designs and PCB layout improvements. For more details on these techniques, see EMI Mitigation Techniques Using the LMZM23601.
