The maximum continuous or mean switching frequency of gate driver cores and plug-and-play drivers is in the first place determined by the resulting component temperature due to the mean load of the components. In view of the transient thermal impedance of the components, higher switching frequencies are briefly permissible.
Due to the large thermal time constants, it can be assumed that the mean power dissipation can be fully exploited for a burst duration of less than a millisecond and a duty cycle of up to 0.1, i.e. bursts with about 10 times the mean switching frequency are permissible.
If this means that the absolute maximum ratings specified in the data sheet are exceeded, please contact the CONCEPT support team for further clarification.
