split rail supply obtain from a single motorcycle battery?
Can anyone help me find a suitable split rail power supply from a single rail of 12 volts battery, like a motorcycle battery so that i can power my electronic crossover ( active filters for subwoofers) without too much current drain on the supply.
is the MC34063 ic can do the job according to its datashhet found all over the net,
i made my first DC to DC converter
12 volts input
13 to 24 volts output at 1.5 ampere
for my chip amps use as a sound system for my motorcycle here in manila,
my problem is i wanted to incorporate the active filter so that i can put a 6.5 inch subwoofer on it to gain attainable bass response without sacrificing my entire motorcycle battery.
CAN ANYONE PLEASE HELP ME
by the way i uses the tda8560q for my ampli.
thank a lot guys
You want to convert +12v To -12V to give +/-12V supply? How much current does it need to supply?
If you only need small amount of current, this device can be used to convert +12 to -12:
OR do you want to split the +12V to give a +/6V supply? This would be a supply splitter circuit, lots of circuits on the net to do that.
If you live in Manila - go to e-gizmo along taft avenue (near De La Salle), get yourself a 12V DC to DC converter module - 12VDC in, 12V DC out. This is an isolation-type regulated -output unit. The module is rated to about 50W out, more than enough if it's just your active crossover you want to power.
Wire up the output of the DC-DC converter so that it's "+" output is connected to the "-" of its input. voila: -12V out.
Cost is P200.
thanks for all of your replies,
though i am looking somewhat a DIY thing and not a ready built one, this forum is all about DIY, right
well, i am beginning to modify a circuit that is related to what i am needing, and it uses the motorola MC34063 ic and according to its specification, it can be modified to produce -12v to -24 volts at 1.5 ampere,
pics will be out the next time
sir Clem_o, if you mind if i ask your location in manila or philippines,
i am glad there are "kababayan" here:)
Well, that's the DIY spirit!
I work right at DLSU actually...
