+/-15V ???

Hi there, im doing a project which uses a PCB mount current transducer, need to supply +15V and -15V to the current sensor. How can i produce this -15V from a 12V or 24V dc battery??
 

Re: +/-15V ???

You can go for a step up DC-DCregulator from maxim for generating +15V
from 12V battery. For generating -15V you can go for a inverting type DC-DC converter from Maxim.

For inverting type upconverter you can use MAX776 -15V or Adjustable, High-Efficiency, Low IQ, Inverting DC-DC Controller

For +15V you can use MAX1633 15V CMOS adjustable Step Up Regulator

The output is taken with respect ot common ground.

For any other combination you can visit

Hi wakaka,
You can use LM2576-15 in below circuit to make -15V regulator (in schematic diagram output voltage is -12V).
Also you can use same IC to make +15V from +24V input, for more information check LM2576 datasheet.
