Hello team,

I have a question.

In section 6.3, tON, is it 10,000 instead of 1,000ns? On time 1 in section 6.5 is 2,550ns (over the recommended value).

Regards,

Masa

hi, Masa,

refer to Equation 3, it is 250n, 75/12/2.5=250ns.

Hi Elena,

Wouldn't it be as follows?

75 / (12 * 2.5) = 2.5 us = 2,500 ns.

I still think On time 1 exceeds the recommendation in section 6.3. Is it 10,000 instead of 1,000ns in section 6.3, tON?

Masa
