Hi,
I watercool my computer but my pump has just died (Again) so I'm looking for a new type of pump which will be more reliable. I've got a lot of suggestions to use a particular pump, however it's 24V and I only have 12V inside my computer.
I'd like to make a 12V to 18V-24V converter. (Adjustable between 18V and 24V, however I expect it to mainly stay on 18V.) The pump draws 2.5A at 24V, which is 60Watts.
I have found this on google: http://www.epc.com.cn/meeting/resource/2005power/download/linear.pdf
However it is a buck-boost converter. I only require a boost converter, so I'd like to simplify it.
So in summery, I need a boost converter to convert 12V to 18V, with the option to adjust the output upto 24V. (Although it will be setup mainly for 18V) The converter must be able to supply 2.5A at 24V, which is 60Watts continuously, but must also be able to cope with the startup current of a motor.
The circuit must be very reliable and must NOT add any noise onto the input power rail.
Here is a link to the pump: **broken link removed**
Any IC used must be available in a DIP package, because I'm on a laptop so I havn't got any software or librarys from Eagle. I'll need to build the circuit on stripboard while I design a PCB for it.
Any chance of a circuit being designed for me, seems as I can't do it on here. (Laptops, can't live with them and can't live without them !)
A list of part numbers available in the UK would get you cookies. :x
I have an oscilloscope and adjustable powersupply so I can test the finished product with no problem. I also have a Peak Atlas LCR meter so I can make my own inductors if need be. (But please tell me what guage of wire to use and the expected number of turns, becuase I have no idea about them.)
Thank you !
