Voltage Doubler Circuit- 9V to 18V

Power / Voltage - Voltage Converter

This is a very simple and easy voltage doubler circuit. It provides 9V DC to 18 DC by using Max 1044 or L7660 IC .The output voltage will be slightly less than double the input because of voltage dropping on the diodes. It can be minimize if  we use Schottkey diodes which exhibit a lower voltage drop. Mostly care of the maximum input voltage of the IC not to be more than 10V. This IC can only take a 10v maximum. Otherwise its damage. So lets go to make it.
