TSM1012

[PG.6]

Hai,

I wanted to make a battery charger using non isolated boost IC. I came across this TSM Voltage and current controller IC. But this IC has been only used in insolated application. Is it possible to use this IC in non isolated converter. I will attach the block diagram of the same.

You should be able to use the TSM1012 in a non-isolated project, as long as the boost IC is controlled by a pulldown similar to an optocoupler.

Good luck!

Hello Peter,

Thank you for the quick reply. Is it okay if i use an opto-coupler for feedback in an non-isolated converter along with TMS IC. Will this be able to charge Li- Ion battery?

Yes, you can do it with an opto-coupler, but that's wasted money.

As I said - TSM1012 could drive the boost IC directly if this boost IC can be controlled by a transistor of an optocoupler. The TSM1012 contains a pull-down structure, which is very similar to that transistor.
