MC33063A-Q1: Adding an external NPN for inverting circuit

Part Number: MC33063A-Q1

Tool/software:

Hi 

I am adding an external NPN BJT for an inverting circuit. While reviewing the datasheet, I noticed that Figure 7-7 on page 15 appears to be identical to Figure 7-4, which seems unusual.

To address this, I created a new schematic for the inverting configuration. Could you please review it and let me know if my approach is correct?

Thank you
