A little help: I am laying out a Solar Array Cell Phone charger card. U1 can switch at up to 500kHz and U4 can switch at up to 400kHz. With this layout I'm concerned the mag fields on the inductors (L1 & L2) will interfere with each other even though they aren't on the same core. Is my intuition correct?
Also, I'm not convinced I need C9, as that is the battery pack just to the right. I'm using LiMH. Thoughts?
