Other Parts Discussed in Thread: LM3481
Hi there, I want to use a boost converter to go from 15V to 24V and have 3A load current. I was originally looking at TPS61175PWP because I liked the size of the chip but with the values listed above, I could only get a max current of 1.5A (please let me know if I am wrong and can achieve 3A on this chip). I then started looking at this chip but I am confused by section 9.2.2.2.3 on the datasheet to calculate the inductor Volt • microsecond constant E × T. When I plug my values into the equation it obviously gets a negative Volt • microsecond constant which is obviously not shown in Figure 30. What do I do now? How do I find the correct inductor to use for the 3A current I need? Am I using the wrong equation?
