TPS54541: Current limit settings

HS FAE Germany

Part Number: TPS54541

Hello,
customer wants to use the TPS54541 to charge a battery pack. He needs Vin=36V, Vout=30V, Iout=1A, 2A, 3A, 4A. Is this possible to set different current limits may be a MCU?

This device does not have adjustable current limit. I would search the TI website for a
device with adjustable current limit.
Alternatively, you could design an external current limit using an op-amp.

Hello Frank,
do you have a suggestion with the OPAmp?

I would use an opamp with a wide common mode input range to take care of the case when vout is low.
