hanges required for using   ADP2300.

Hi,

I am currently using RICHTEK -RT8258 for 12VDC to 3.3VDC stepdown in one our product. Now i would like to use ADP2300. But i can't change R1 &R2.  From 100K and 32.4K to 31.6K and 10.2K.  For EN i have directly connected to VIN.Whether the design work?

    Hi Naveen,

    Yes you can use 100Kohm and 32.4Kohm for the feedback divider. As long as the bottom feedback resistor is less than 40 kohm, the output accuracy degradation due to the  FB bias current (0.1 μA maximum) is less than 0.5% for the ADP2300. The absolute max voltage rating of the Vin and EN pin of the ADP2300 are the same, and they can be connected together.
