12v to 33v dc to dc converter

[demetal]

Hi,

Can anyone suggest a circuit to convert 12v to 33v....


Thanks

You can use LM350/LM350T Adjustable Voltage Regulator IC.
Specifications:-
Current: 3A, Regulator Topology: Adjustable, Regulator Type: Linear, Output Voltage: 1.20-33V, Feature: Output Voltage Adjustable.

Manufacturer: National Semiconductors, Manufacturer Part No: LM350T, Package / Case: TO-220-3.

Othervise you can also use zener regulators.
Hope it helps....

What current and what efficiency range ?

Amazing.

Hey, if I use Zeners AND am LM350 can I get 66V out??

I'm afraid that that is already patented by WidElectronics.

What is required current for 33V?, Is isolation required?,What is the efficiency expected?

Sorry, but i didnt get the point of isolation in dc to dc converter!!!!

Never mind that for now. Better go back and read up on principles of linear voltage regulators...

Isolation not required if 12 V is a battery source. Isolation required when the 12 V ground is connected to high voltage ground.

Back to the OP's question.

How much Current do you need ?
Do you require the 33V to be isolated ?

My experiments with boost converters. The 2nd link has two desigs, one uses a 555 and the other a ncp3063. Both 27V but higher is no proble.
The first link can deliver high currents.
