Hello there.
I've piggybacked three chips, for a total of 2.6A (2 1A chips and 1 0.6A
chip, piggybacked with heat sink compound slathered between all the chips
and between the top chip and the heat sink I've put on it). I haven't had
any problems with this setup, but that may just be because I haven't had
the time to play with it much lately.
Hope that helps...
