New TPS61200 Circuit

Aww I want a rework station ...

Anyways heres an update of the schematic with correct values.. i think..

My dad thinks C5 is a good idea. I don't know if we need it. I'd like to get rid of some capacitors because we have a lot and it takes up a lot of room on the board. I dont know... Any comments???

The sch looks fine, so do component values. I'm not sure how C5 would affect the performance (probably leading to a shorter power-up spike?). My version with LM3410 works fine without it, but I'm putting it tomorrow to see what happens. I assume C5 should well be in the picofarad range, as both the output of the current sense chip and FB input are high-impedance terminals.

sounds good. let me know what it does. yeah too big a value might cause oscilations..?.? anyways yeah... I have to redesign this in eagle because i NEED autoroute... SO hard without it.
