Hi,
I need a switch mode lead acid battery charger for a 12v, 200Ah battery.
Any link or schematic?

Thanks

Dear Max,

Although I do not have anything specific for you still I suggest you take a look at gevv's post modding a PC SMPS. If you could tweak it to supply 13.8 volts and the current limited (constant current sya @ 10Amps ) you get a battery charger. With the voltage steady you won't be able to overcharge the battery. Don't forget to put a diode between the PS and the Battery. Otherwise your regulation loop may go weired. For more smartness you can use a micro to control the whole thing.
