Hello,

I am working in calculating WCCA. I am looking for minimum Dmax value.

Please advise,

Thanks,

    Hello Arun,

    You can calculate the maximum duty factor while maintaining frequency using this device’s minimum off-time. Minimum off time is listed in the datasheet and has a maximum 125 ns. At 2.1 MHz, this gives a worst case maximum duty factor of 73.7%. If a higher duty factor is needed to regulate, frequency is automatically reduced.
