Hello,
I downloaded from the TI into a MATHCAD document, is the design calculation of the corresponding SLUA312, there is a place on this document I doubt, I do not know whether to help solve, the following is my question:
To calculate the Rslope, the calculation is to first compute the Delta I (Islope) when the current drops, and then through the conversion relationship, which is multiplied by the number of CT loops than the ACS, and multiplies the sampling resistor rsense.
The problem is that I can also calculate the delta I results through the ton process as the descent process, because the Volt-SEC value must be balanced. What does it mean to take the descent process?
Since it is to get the inductance current down along the slope, it should be (vout/lout), this is the slope, so I do not understand this method of calculation, please help me to solve this doubt, thank you!
