I hope I'm not getting mixed up here, but it looks like there is an error in the first paragraph of section 8.2.2.3 (pg 41) in the data sheet. The ds says "...the equivalent capacitance of CCLAMP [on the primary] reflected to the secondary side (CCLAMP/NPS^2)", but shouldn't that be (CCLAMP * NPS^2), or (CCLAMP / NSP^2)?
Assume that NPS = 2:1 in an ideal transformer, then looking into the primary the impedance of the secondary would be 4x, or the capacitance of a capacitor would be 1/4x. Looking back the other way, the impedance of the primary looks like 1/4x from the secondary so a capacitor on the primary would look 4x as large. In other words a capacitance on the primary seen by the secondary would be Cpri * NPS^2 or Cpri / NSP^2.
Am I or the ds wrong? What's the verdict?
