hi all

can i drive a 6 volt relay coil with 5 volt / 2 amp source?

thanks in advanced

Maybe

Maybe

any ideas?

i tried to use 2200 uF capacitor in parallel with the 5 volt source but i failed. :confused:

Your relay and supply are both DC?

Then it needs 6 volts to pick.

If you have a switching power supply you would be able to raise 5V to 6V.

A 6volt relay should kick in with >=4.5volt, but slower.
That might or might not be a problem for the load it has to switch.

You might have to use a mosfet for the coil. A transistor drops another 0.5volt.
