I am going to install two devices in a car.. one device needs +ve pulse and second need -ve pulse.. for the pulses i am going to take supply from the battery... For giving pulses i will fix a single push button in the car... if i press the push button both the device should get the pulses.

Why don't you use the 12V car battery as the +12V pulse source and purchase an isolated +12Vby to -12V converter for the -12V pulse.?

hi,
The problem is to convert from an isolated +12V to a -12V at say 2Amps will require additional circuitry, not just the switcher IC.
You can buy ready built modules from eBay etc... I will check it out and post.
