Hi Sir,

The Datasheet is show the Ton=15ms form Table2, but Equation 15 key in 0.012.

Why is 0.012? not 0.015?

What's the Ton Rang Max & Min?

Hi Hugo,

The 0.012 sec seems to be a typing error. The result of 0.48 uF is still correct as it considered 0.015 sec.
The variation in ton can be calculated by taking variance in the parameters on which it is dependent on in equation 5.

Hope this helps.
