I am looking for a way to construct a 1 A, ±15 V split-supply. So far, I've seen a number of designs for split-supplies (http://tangentsoft.net/elec/vgrounds.html), but they are all low current (i.e. 100-300 mA).
My application involves several Mass Flow Controllers that each require a +15 V, 0V, and -15V connection. The data sheet says they draw 300+ mA when in operation (they contain a small heating element).
I attempted two separate solutions using an LM7815 and a LM7915 (one with and without the voltage divider), but they did not work.
Can someone point me in the right direction of an appropriate circuit?
