DI-12 battery charger Design Idea
Posted by: cjf3rd

I need to design a battery charger for 48V lead acid battery with high line only input. Do you have any docs or design software to help me modify DI-12 for my requirements? I also see that the TOP244 is not for new designs, so I would need to know what part to use instead.
I would recommend using the TOP-JX series for this application. The actual part number/package type will depend on the output power of your application. You can estimate max power requirement by assuming battery id charging at max voltage delivering max charge current..
You will need to download and install the PI Expert suite of design programs, available at the Power Integrations main web site. As an alternative, you can also use the PI Expert online tool.
It is best to treat this as a new design, as there some significant changes between TOP-GX and TOP-JX.
