AD5242 for i2c controlled voltage regulator

Hi,

I am using AD5242 in my design as a digipot for controlling one of the feedback resistors on a linear voltage regulator ,LTC3615. I can read and write the i2c values on AD5242, but do not see any resistance change at the output and hence no voltage change at the output of the linear regualtor. Any help appreciated.

Thanks,

AJC.
