1.5v to 9v dc converter circuit

This inverter circuit will convert 1.5v to 9v to take the place of those expensive 9v batteries.

The input voltage for this inverter can be from 1.5 volts , up to 4.5 volts . When no current is being drawn from the output the current is less than 10mA.

This inverter circuit is very simple requiring few components , but it can be used only for projects that require low current . The L1 coil must have 60 turns on a 10 mm ferrite slug 15 mm long , using a 0.25 mm diameter enameled wire .
