SMPS Cum Battery Charger

[jackadam]

Dear All,

I want design SMPS with battery back up for long time.

But my charging current is very low approx. 2Amp but i want to increase it.

I want design the system with following specifications:

Output voltage : 12-15VDC
Load current : 4Amp.
Battery charging current : 6Amp.
With overload protection

Can anybody help me?

Is it worth the effort to design your own?
