2008-10-16 EMC issues for hysteretic converters in LED driving
The use of LEDs in a wide range of lighting applications is rapidly increasing. In order to maximize the efficiency improvements that the LEDs offer they must be driven from switching regulators rather than power hungry linear circuits. One of the most versatile inductive switching topologies is the hysteretic converter. To ensure these converters are used effectively in a fully EMC compliant manner their limitations must be understood.
