3.1 Maximum Output Current

In IBB configuration, the inductor current and peak switching currents are larger than in the equivalent buck converter. Consequently, the output current capability in the IBB topology is less than the buck configuration for the same current limit specifications.

Figure 3-1 provides a general idea of the recommended maximum output current from the TPSM5601R5H-IBB-EVM.
