    CYPD3171 and CYPD3175

    byhoc_3774811

      What are the differences between CYPD3171 and CYPD3175?  Datasheet shows CYPD3171 being used for Power bank applications and CYPD3175 for power adapters.  What characteristic makes one suitable for its intended use?

       

      Also, in some application circuits VDDD is driven from an external 3.3V regulator and in some other applications it's driven internally from the VBUS_IN.  Why?

       

      Thanks in advance.
