Can I use DAC interference TPS40170 ILIM to achieve programmable current limit

Other Parts Discussed in Thread: TPS40170

Dear Sir/Madam,

I have a design which implementing TPS40170 as buck regulator. My input voltage is 17.5V and I use DAC interference TPS40170 voltage feedback to achieve programmable output from 0V - 15V output.

I am thinking to add programmable output current limit feature also and TPS40170 which use resistor set ILIM. I am thinking use DAC to interference this pin also to achieve programmable output current limit. is it possible? Any reference or comments for me on how to to the calculation to set DAC output to achieve this?
