In the inverting buck-boost topology, the maximum output current is reduced as compared to the buck topology. This reduction is a result of the peak inductor current being higher, as calculated in Equation 4. With a power module, there are additional thermal limits arising from the small size of the power module itself. Finally, there are further limits on the maximum output current that occur from stability due to the right-half plane zero, which occurs in the inverting buck-boost topology. Figure 4-1 shows the maximum output current based on temperature rise and stability for the TIDA-01457 design. The current limit for the TPS82130 device occurs above all curves in Figure 4-1 and therefore does not limit the maximum output current more than thermal or stability limits. The current limit itself still operates to limit the peak inductor current.
