Hi,
I have some questions regarding designing of LM25148
- Is it necessary to have RC network across inductor and current sense resistor?
The datasheet says that if need to measure current using inductor DCR current sensing then need to use it. I have very tight space so i don't want to use any extra component on the board. - I don't know the nominal voltages. It can be any in between 9V to 36V because i have to connect it with various power battery sources so each battery source has different nominal voltages so what i should consider in that case nominal voltages?
- In my previous design, the inductor is collapsing. I did some research and i believe it is because of saturation current exceeding. As soon, the current raise above 9A then board shutdown or cause abnormal output. I have to design a board for 15A current. What should be the ISAT and current rating of inductor is safe considering input voltages 9V to 36V and output 7.4V or 8.4V
