Hi,

I have seen calculation for Lboost. I am asking about the resistance calculation for boost converter. How to calculate the other parameters of Boost converter. The parameters which are attached in the picture.??

RLBOOST is the boost inductor DCR in Ohms. This parameter will come from the inductor datasheet.

The other parameters such as CSGAIN, RSSW, CRESP are internal device parameters, which are fixed.

Hi,

Thankyou for your answer. For the calculated Lboost value how to find RLBOOST value. Where was the inductor datasheet available??

I didn't make this model, but I suspect they just chose a typical value for RLBOOST as this is an "average" model. If you have a specific inductor in mind, you can substitute the value from that inductor's DS in for this parameter.
