Other Parts Discussed in Thread: TPS62840
Tool/software: WEBENCH® Design Tools
Hello,
I did a Webench design using the TPD610997. 1.6V to 3.6v input, 5V output at 100mA. The design selected a very expensive input capacitor: a Panasonic EEHZC1V151P 150uF, 35V cap which costs $2.59. Is there a particular reason why this cap was selected? If you look at the datasheet, on page 17 it says that a 10uF is normally recommended. I was wondering if there was something in particular about this design that makes this large cap necessary. Thanks you!
