Writing design notes
I need to write design notes that include component selections and the power budget, probably later. I should also add components. First, I want to get property config for a generic package, which might involve querying options for that package. Maybe I could skip including specifics like resistance or capacitance for now. I’ll try omitting the designator and see if it returns standard options that cover multiple choices.
Evaluating capacitor needs
I’m considering the capacitor requirements for my project. For C1, I’ll use a 1uF eFuse CIN. For C2, a 10uF eFuse COUT sounds good, and maybe I should stick with that. C3 will have a 1uF for LDO input.
