Hi, i want to use this voltage doubler http://www.farnell.com/datasheets/43302.pdf in order to be used with a bistable relay **broken link removed** .
the voltage doubler will be switched using a microcontroller, and the voltage doubler will be applied to the relay the relay is 5 VDC, so i have only 3V, in the relay i have to coil so i need two voltage doubler, can you provide me a solution in order to use only one voltage doubler for the two relay ?
 

I do not understand your question. If you want to control a 5V relay from a 3 V source, then one voltage doubler would do - 2 X 3 = 6V. So take the output from your micro, use it to switch a transistor on which earths the end of the relay, the other being wired to the new + 6V line.

no but the two relay have to be switched separately, and in my relay the two coil are connected together. so i can't switch the two relay together.
 

You only need one voltage doubler. Pin A3 on the relay is always connected to plus. To operate the relay, connect pin A2 to minus. To reset the relay, connect pin A1 to minus.
