6V to 12 volt converter

6v to 12v converter

I have a 6V SLA battery from which I want to generate 12V
now battery voltage can vary from 4.8V to 7.2V

few of the IC's from Maxim like max1771,max771 , national's LM2577 etc i have seen. but these are not available in my city.

So I am planning for discrete also.

If you are suggestion any IC plz see that it is very very widely used like LM7805.

I was not able to get LM78S40 universal switching regulator.

Have you tried MC34063 (MC33063) Control IC.Easy to design and widely availiable.

Spice models with ready made examples of various topologies are here,

You also may want to look at the UC384X current mode controller,also widely availiable.

Spice models are availible here,

Also google for "charge pump" this might fit your need.

6 to 12 volt converter circuit

I have gone through this
h**p://www.aaroncake.net/circuits/6-12conv.htm
But I need more proffesional one in which I can use some ready made inductors available

I would like to add that this link is very much popular in 6-12V design. cause most of the schmatic collection sites ends on this link.

I was looking for some thing different.

Added after 3 hours 8 minutes:

Also google for "charge pump" this might fit your need.

Charge pump cannot give 1A@12 from 5-7V input.
I am not sure but it seems to be.

6 to 12v converter

I got this IC and at very low cost.
MC34063
Now I will start designing with this.
I have multisim simulator but this IC is not there how can i add this IC

can i use spice model from
