Voltage Doubler Circuit using 555 IC
Posted by Rohan on Thursday, August 07, 2014 with No comments
A voltage higher than the supply can be created by a "Charge-Pump" circuit created with a 555, diodes and capacitors as shown in the following circuit. The output will deliver about 50mA.
This can be used for those components which require around 12v and the supply you have is around 5-6v , thus this is a very handy circuit for electronics DIY projects.

COMPONENTS USED :
1.one 555 IC
2.one 1nF ceramic capacitor
3.one 100nF ceramic capacitor
4.one 33K Resistance
5.two 22uF Electrolytic capacitors
6.two IN4148 Diodes
7.one 5-12V Supply
(NOTE : i have used combination of capacitors to make 22uF )
