We use the MP24943 in our design to convert 48V to 12V. As the "Figure 3 Detailed Application Schematic" seen in the datasheet of MP24943(also attached below)，we have questions ,
What does the Vcc needs to be connected with? Can this Vcc be connected to Vin-48V? Can the NS-BAT54S be applied in the application of 48V to 12V?
