What's your supply voltage?...5V?...15V?...?
What 's the load on the +/-15V pulse output?
Is the output pulse in-phase with the 5V pulse...or inverted?
Create a 30V rail and use a divider to create a +15V point to use as a virtual ground (return) for external circuits. Pulse swinging from 0 - 30V will be swinging +15 to -15 with respect to the virtual ground.
How long are the 5v pulses and how much current will it deliver? And how long do you want the +15/-15v. The whole thing requires much more explanation in the requirement, for anyone to propose an answer.

I am just trying to convert a 0-5v square wave to a +15/-15v square wave. Let's say with a 50% duty cycle and frequencies of up to 2.5kHz. I would like the phase/timing of the output wave to be reasonably close to that of the input wave but it is not critical. The output wave shape is not super critical as the device I am driving is concerned with the zero crossings. As far as load, the output of this circuit will drive a couple of opamps.
The overall precision of this circuit is not super-critical and does not need to be commercial-grade. I am just using it for bench testing for some controller development.
========================================
Update: I found a 5V to +/-15V DC-DC converter. I drew a quick schematic and attached it. Based on what all of you kind helpful folks have offered, this is my interpretation of what I should do. Can one or more of you please confirm that this concept looks correct?
Thanks in advance and sorry for being such an electronics neophyte
Go with the op amp solution...very simple...however you do realize (if we haven't explained) that you will need a bipolar power supply...one with a +15VDC/0/-15VDC output.
The a transistor circuit (very incomplete) gets more complicated than shown and gets into the problem of ground references between your input signal and your out load.
Thanks (again), Ken...I mentioned in one of my earlier posts that I found a 5V to +/- 15V DC-DC converter. Is there any reason that won't do the trick?
