This is bugging me a bit, Instead of a LM338K Im going to use a variable SMPS IC to replace it, and to give me more efficiency (along with size). The Chip I will be using is a MAX1745 buck converter. Its not the chip thats bugging me, its the design.

Iripple is Given 2 ways;
Iripple = (Vin-Vout)*1uS/L
Iripple = Vout*2uS/L
Which do I use? One gives a higher Ripple than the other. Using the 2nd formula I get a ripple of 16A!
Oh, here are my specs and such..
Vin (min)=11.45
Vin (Max)= 16.46
Vout(min)=2V
Vout (Max) =15V
Iout Min =0A
Iout Max = 4A
