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?

Thanks,

James

Hi James,

 

The Vcc should be connected to a 5V bias. Higher voltage may damage the IC. The BAT54S should be connected to the left side of R777 instead of between R777 and C1096. For 12V application, we do recommend to add external bias to BST. 

 

Thanks,

Kevin
