+/-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

Re: +/-15V ???

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.
