Hello,
My customer have some questions about UCC2897A.
[Q1]
How many numbers of the maximum duty cycle can it set ?
Can it set more than 70% maximum duty cycle ?
[Q2]
It is described that Ron=Roff=75kohm(NOM) in RECOMMENDED OPERATING CONDITIONS of datasheet.
Is it necessary to do or just an example?
[Q3]
Can Ron and Roff make a different value ?
[Q4]
My customer set the timing resisters as follow.
Ron = 87.6kohm
Roff = 68kohm
Rdel = 18.2kohm
At the time of setting mentioned above, how many is the numbers of the maximum duty cycle ?
I calculated it using the equation (1) to (5) of datasheet.
It was 68%.
Is it right ?
Best Regards,
Hiroshi Katsunaga
