Hi,
I'd like to ask about UCC28950. Coud you advis me 2 questions below?
--------------
(1) measuring on duty
I think on time is "the time between outA(fall edge) and outC(fall edge)", and 1 cycle is "the time between outB(fall edge) and outA(fall edge)".
*on duty=on time / 1 cycle
Is this correct way to measure on duty?
(2) Maximum on duty
In datasheet P.3, Max duty is 95%(typ)@Rt=59kΩ.
My customer measured max duty by method(1) , He said the resut is approximately 97%@Rt=68kΩ and 90%@Rt=22kΩ.
It seems the frequency lower, max duty goes higher.
Is this function correct?
