Conversion of 5 v to 24 v

[falcon98]

Hi

I am using a SPARTAN 3e fpga to provide 2 pulses of 5 v to the field. THe field deviced work at 24 v .
SO i require help in designing a 5 to 24 level convertor.
Please let me know how can this be achived using transistors.

Hi,
LT1930/LT1930A is a Step-Up DC/DC Converters which converts 5v to 24v. This is one option.

I think falcon98 need a logic level shift IC, not a voltage converter.
Ordinary shift IC may could not provide so big difference shift.
You can search on some website like TI, Maximum.
If they could not provide ICs satisfy your require. You may try coupler.

You can just translate the digital signal from 5V to 24V using an npn transistor for example.
It is quite simple. Unless you have other constraint, a transistor would be good enough for most voltage translation function.
The follow is a link which explain in simple illustration how a transistor can be use for converting the voltage logic that you need.

Try with voltage doubler's or charge pump (Dickson charge pump)...
