Hello,
My customer is having a question about the timing ckt of UCC28950
The particular application is sensitive to wide frequency variations, so I am attempting to determine the worst case frequency range.
In particular I reviewed the datasheet (SLUSA16B - http://www.ti.com/lit/ds/symlink/ucc28950.pdf) and equation 10 is used to ‘set’ the frequency.
A few questions:
1) The equation appears to be an estimation of a more detailed equation. Can you provide any details on this equation (block diagrams, detailed equations, etc..)
2) The equation that is present in the datasheet does not have consistent units. Because of this I cannot determine if the “+1” in the denominator should have precedence over the “x kOhms/V”. In other words, should the equation follow normal mathematical precedence (multiplication prior to addition)?
Thank you very much!
