[dorkbotnyc-blabber] Circuit Help

Hello

I am trying to figure out how to make this PIR sensor work that I just  
bought with another component I need to use.

data sheet:
http://www.electronics123.net/amazon/datasheet/kc7786.pdf

Basically, I light electroluminescent panels with these special high  
frequency transformers, they run on 12vdc. I have been running them  
using this 12vdc wall transformer, it is regulated a 1 amp with no  
problem. However when I connect the PIR sensor the output voltage  
becomes 12vdc at .2 amps and this is too low to drive the transformer  
and therefore won't turn the light on.

So, I need the slightest boost. It has been suggested to me to use a  
relay. This is where my confusion begins. I have been reading about  
them, I understand the premise, but I only need a slight bump up of  
the amperage not voltage.

I have also been advised that due to the sensitivity of this PIR  
circuit I'll need to protect it from the electro magnetic pulse  
discharged from the relay when switching off.

Can anyone help me here?

Thank You!
Alex
