TPS92691: Buck-Boost topology Q4

Part Number:TPS92691

Dear support team

According to the DS Figure 26 der PNP transistor for the OVP is connected as following:

Base -> Input/LED-
Emitter -> [Res.] -> Output/LED+
Collector -> OVP

However in the design example Figure 41, the connection is as following

Base -> Output/LED+
Emitter -> [Res.] -> Input/LED-
Collector -> OVP

Is the connection in Fig. 41 wrong or why is the bipolar in the design example connected differently?

Thanks and best regards

Raphael
