# The many DC to DC converters using IC-555

Posted on Feb 5, 2014

This be Simple Doubler Voltage circuit, from voltage 12VDC to be 24VDC. By use Timer IC highly popular the number NE555 and other equipment a little again. It can give current get about 50mA convenient for the circuit, that use low current the small-sized. The principle works of the circuit be, When use Volt input 12VDC give with the circuit will

touch Filter current smoothly with increasingly. The capacitors C5 give with IC1, The resistor R1, R2 and, capacitors C1, Which build the circuit model astable multi vibrator Square wave generator, at the frequency about 2KHz come out the way pin 3 of IC1. By have capacitors C3, C4 diode D1 and D2. Which build be boost up voltage x 2, which will enhance the level Volt out be the direct current about 24VDC or 2 times of the level Volt input. This circuit is called DC TO DC converter circuit. Which increase the voltage circuit. There can be customized to change the output values. For example 6Vdc to 12Vdc, 12Vdc input to 24Vdc output. When the power supply input to IC1-NE555 is the output pin 3 at a frequency of 1 kHz. The frequency is Q1-BC547 and Q2-BC557, which will continue to use push pool work interchangeably. If this is the positive output signal Q1 Q2 will run the delete function this reason, C2 and C3 capacitors are half-wave alternating. To test the circuit or circuits that may need some circuits, but we have no fire-5V power supply-5V, but if the battery 9V circuit can allow us to use the volt-5V as desired. By using IC NE555, which causes wave square the sector output allows the voltage about 6V when the signal on the output from a pulse plus C2 acts charge through D1 to ground and if the pulse negative capacitor C2 will discharge. through diode D1 and capacitor C3 to chage that negative voltage is about-6V, but...
