Other Parts Discussed in Thread: UCC28061

Hello

I had question from customers about culculation process of formula (23) I cout_HF in P26 of UCC28061 datasheet.
They would like to know that why I cout_HF can culculate by using RMS current.
Can you answer this question?

Best regards,
Mitsuo

    Hi Mitsuo-san,

    My understanding of your question is that the customer wants to know how the formula (23) calculates the HF rms current?

    Is that correct?

    Regards

    Hi,Peter-san

    Customer question is "Why does calculation formula of I cout_HF include only RMS current ?"
    Because customer thinks its formula need to have both master diode current and slave diode current
     or its formula need to delete DC cuurent value from diode current.
    So customer cannot understand why its formula has only RMS current.

    Can you answer this question?

    Best regards,
    Mitsuo
