Voltage converter using 555 timer IC

DC to DC voltage booster using the 555 timer IC. Note: I said "voltage" a few times where I meant to say current.

that's pretty cool, and even with the low 200mA current (or 100 on the cmos version), that's still enough juice to run some circuitry off of a smaller dc battery. cool video, thanks for sharing!

Actually much less current. Since it is switching, and boosting voltage (less current), the over all current is much less. Adding a complementary pair of transistors to the output would allow for higher output currents.

@dmctactic It is not for commercial design. I got several 555s for free so cost is a non issue. This was mostly to show how the voltage doubler effect works.

@vegmatic1966 Well I thought it was interesting! The 555 is such a great chip, you can do hundreds of thngs with it in many different types of circuit...

Thank you for sharing this.

try to use AN7812 the 9 volts will be at 13 volts the IC max upto 3a.. you must bias the Collector to the Base instead Emitter to Base...

Thanks, its always interesting to learn something new. If you are using it to

power something producing audio , I would imagine that it should be of a

frequency above the audio range too.

It is sort of like the AC voltage doubler principle of charging two caps in series

to double the voltage but with a square wave from a DC source

Thanks for posting this, coils and transformers are not my specialty. But if you increase the value of the cap to say a few hundred uF, and increase the 555's frequency, would that increase the voltage? Or is there some formula I can use?

Very well done, interesting and I learned some--thanks1
