I am searching for a 220vac to +5VDC converter / regulator chipset.
Can someone suggest of other chip that provides the the given conversion. I've seen one from MAXIM (MAX610, 611, 612), it is a chipset that directly converts 110/220vac to a regulated +5VDC (or even variable 0 to 17VDC) but I still need other options.

Dear All,
I need to make a converter from 220vac to 12vdc -4A to operate a solenoid
i required this circuit for pulse shot only (800ms -1s)
please tell me any circuit i can not use Transformer .
only linear circuit.

You haven't specify AC power of the motor ..
If ≈500W is enough then here is a low cost 12vdc to 220vac inverter:

How do you mean only way? Can you elaborate and give us some light on this?
I mean to get 300vDc from 12vdc in high power without any type of Transformer(Iron or Ferrite).
What you will get if you put Graetz bridge on HV mains (220V) ?
yes you are right you can get 310v DC

Well, let me tell you a bit more,...
I'm planning to make a IPS (Instant power supply) (a backup power). It will be AVR based. The say mega32 will first observe the 220vac mains. meanwhile, the ADC will take reading (2 ADC in that case for differential V) for charge current. The charger is not 3 stage but 2 stage. Upto a certain Current flow, it w

Can't you generate 80kV, 100kV and 120kV directly from 220vac ??
Why would you go down to 12vdc and then step it up to kV ??

Yep, it's bloody dangerous, I know.
Unfortunately, I can't tell you what is the energy source exactly but don't worry it's nothing nuclear and absolutely nothing unlegal.
In short, it's sort of static energy collection system wich goes through diodes to become DC in order to be stored in large high voltage oil capacito

Now I want to know what if you dont use 340 VDC and instead run the H bridge stage with 12 VDC source.
Now to have working voltage of 220vac, use a 12-220 VAC step up transformer at the output of the H bridge. Will the circuit still work. Guys your feedback would be appreciate.

so you thik that it will be easier to make 220V AC(sine wave) from 12vdc converting (Busting up) into 400V DC & then sepping it down into 220vac?? but why are you suggenting this intermidiate stage? loss may occure here, isn't it? and what should be the configuration in the second step? please give some detail information.

Was quite helpful, but that is very much different compared to SMPS type of adapter. Whats there in the link is DC to DC convertor, but in a AC to DC converter we don't convert the AC to DC and then again convert DC to DC. I'm little confused about this. We don't use a transformer to directly step down 110/220v AC,

There is no need to design a V to I converter only for relay driving .The 12vdc cradle relay is a very economic product and available off-the-shelf at any point .The same is available in lower current ratings too ,if desired .The Goodsky 'G series' draws 8.0mA at 24 VDC and very reliable . Contacts are 250VAC/5Amps rated to drive your 110VaC .

I guess you might have wrong information on your side.
220Vdc seems to me that it should be
220vac.
You can try using Seal Lead Acid Battery 12vdc.
Choose a big battery if you want the power to last longer.
A 7Ah or 7 amphere hour batter can run
a device drawing 7A for one hour,
or a device drawing 1A for 7 hours.
