Many 555 DC boost converter circuit

If friends would to want the DC to DC voltage converter is small that has a few output current.
I would suggest the IC-555 timer DC boost converter circuits is a key equipment that it is popular and easy to uses so can be used in many circuits.

Doubler voltage 12vdc to 24vdc with NE555

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.

DC to DC converter using ic NE555

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.
When to use. Voltage from C2 to C3 is discharged out to the input voltage over almost two times less than 2 times due to the loss of diodes D1-D3.

9V battery changed to -5V

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 being removed to the number of left-5V zener diode ZD1 current output will be approximately 12mA.

Negative supply voltage low current

This circuit is a negative power supply integrated. Which can be applied to circuits that do not need much flow. Using IC No. 555. The core of the circuit.
Work of the circuit is IC1, R1, R2 and C1. The range of the A Stable Multi Vibrator, and the output is a square wave. It is a positive signal pulse frequency of 2.3 kHz output pin 3 of IC1.And C3 and D1 connected to circuit CLAMP. That it serves to signal a positive pulse to pulse signal negative.The D2 and C3 act negative pulse signal is converted direct current (DCV) electrical signals. The negative power. Thus the output voltage to a negative DC electrical.

Power supply positive-negative-ground from a single power supply

I like to try different circuits. Using adapters as a power source. Which it has disadvantages be it can not turn on the negative power supply.
However, this circuit can supply both positive and negative.
This circuit is used IC number NE555 set up to stable multi vibrator.It produces a frequency rectangular patch of about 100 Hz.Out to pin 3 through C3 and C4. Before the rectifier power section. Both positive and negative DC 2 series.Positive power supply will work with the rectifier D1 and D2.When a positive signal to be via D2 to the output.

And filtered from C5 to filter the pressure to smooth again. But if there is negative signal to the D1 and down through the ground.The negative power of the D3 and D4 the rectifier.When a negative signal to the output signal to be via D3. And will be filtered from C6 to smooth again.When a positive signal to be via a D4 to ground.

Note: These circuits worked well as video below.
