Can I use the ADP1872 to design a bidirectional converter?

    The ADP1872 is synchronous buck controller.  Theoretically, synchronous buck converters can be used as bidirectional converters.  So keeping that in mind the ADP1872 should also be bidirectional (i.e it should be able to deliver current from and to both sides if required). Is it so ?
    
 

    
 

    
 

    
 
    Thank you!

      Hi Dhiogo,
      
 
      As I said the ADP1828 will work very well as a bidirectional converter.  Simply run a voltage into the Track that is less than the reference voltage and appropriately size your resistive divider from the output voltage to the feedback pin.  There is no information on the datasheet for this application since it is not very common.
