LM5118: CC and CV mode

Part Number: LM5118
Other Parts Discussed in Thread: LMP8646

Hello Team,

So we wanted to use the LM5118 to design a CC and CV mode buck-boost charger to charge a battery.The input is 48V,6.6A from DC adapter and the output would be 54.6V with a current limit of 3A. We noticed that there is a Current sense pin on the LM5118 with a sense resistor. We came to know that to achieve CC and CV with a controller we can use the LMP8646. But in case of LM5118 do we need the LMP8646 or if we just design it according to webench design with a cuurent limit of 3A will it act as CC and CV to charge the battery from 42V to 54.6V.

Thanks
