Hey guys.
Im designing a SMPS for charging 10 series li ion battries. I want to have a 42v 2A unit.
My question is that with the ICs having no current sense resistors in primary or secondary will the current be limited only by calculating the transformer winding turns or should i implement a current limit on the secondary or i should use a switching IC with external or internal sensing resistor?
