Dear All,

I am in a position to use only 3.6v battery in my device. But, I have to operate 12V 450 mAh device (Alarm) for 5 minutes. How can I convert 3.6v (1500mAh) to 12 V 450 mAh? Earlier, I have decided to use L741 IC. But it requires +/-15v. So, I can't able to incorporate into my project. Is there any other way to convert? Pl help?

Advance thanks.
