TPS7A7002 configured for adjustable output

Other Parts Discussed in Thread: TPS7A7002

I need to control the output voltage of the TPS7A7002 from 2 to 6.1V.

I have connected a regular R1/R2 combination of 150k and 15k respectively but also drive current into the FB point through another 121k resistor driven by a DAC.

Can you see any problem with this approach?

Thanks
