①The tolerance of resistor 825kΩhookuing up ss pin as outside
synchronous behavior.
When synchronous signal input SYNC pin from outside, the datesheet is written to connect resistor at 825kΩ
In parallel, but How many acceptable range is this resistor ?
Presently, I architect part of additional voltage slope of UCC28950, and I would like to question about
TI SLUA560B "UCC28950 600-W Phase-Shifted, Full-Bridge Application Report.
②Variation calculation formula of trance excitation current of
formula 144
I calculate ΔILmag by off duty(1-Dtyp), but if I think how to apply voltage to trance, I think on duty how to calucurate.
Why is off duty?
③Vslope2 calculating formula of formula 46
I understand this division by trance winding fraction a1 to convert current amount of change dILout to 1dimension, but it divide 2 in addition.
What is this reason?
