TPS43061: Over-current Limit Threshold for TPS43061

Part Number: TPS43061

Hi,

I am using TPS43061 and would like to limit the current at 5 A. In fact that would be the normal operating current of my downstream application. From the datasheet I see that we can limit the current using proper selection of Rsense.

As per the datasheet "The maximum current sense threshold VCSmax sets the maximum peak inductor current, which is the sum of maximum average inductor (input) current, Iave_max, and half the peak-to-peak inductor ripple, ΔIL . Choose the sense resistor value based on the desired maximum input current and the ripple current, which can be calculated using Rsense = Vcsmax/(Iave_max + Delta IL/2)."

My question is can we use this DC-DC IC without additional current limiter/regulation in the downstream application?

Would appreciate your help in answering this.

Thanks.

Vijay
