TPS62933: Regarding design & simulation tool for inverting application of TPS62933

Hi 

could you follow below apps notes for Inverting buckboost design

Create an Inverting Power Supply Using a TPS6293x Buck Converter With Internal Compensation (Rev. A)

Hello,

Thanks but I had this appnote. The basic question stands around stability of the design. Question is do the equations in the design are fair enough to predict stability? 

I am trying to figure out the way with some tool to build confidence before going into actual design. Like we designed using the appnote but is there way to see its performance like for other ICs?

Hi 

1. for inductor, follow the apps notes for inductance choosing

2. for the output capacitance,  choosing >47uF effective capacitance will be helpful to the loop stabilize 

as we don't have proper tools for the loop simulation, customer can set up EVM for Inverting buck boost and do the loop test .
