Is this LMZ22010 module a fair candidate for a programmable supply via pot, I2C pot, DAC, etc.?

Thanks for the reply Michael.
I need to design a supply for a programmable output up to 12VDC. The LMZ series seems a likely candidate for this.
TPSM series does not seem to accommodate the output range I need.
I just wanted to know if there were any negatives to using the LMZ modules in this way.
(These modules would dissipate a lot less heat than a comparable, linear LM317 type application)
The PTN78020W looks like a winner for my apps.....
I took a look at the data sheet but could not locate one particular pc of info. There is a PTN78020WAD and an PTN78020WAH available; both through-hole pkgs,
However, I cannot find a definition or the difference between the WAD and WAH suffix.
Both WAH and WAD are identical.
The device was originally released as a WAH suffix, before the Pb-free initiative. The device was converted to Pb-free in ~2005 and at that time we released the WAD suffix. Since then, the WAH was also converted to Pb-free. So now both devices are identical. Both devices will continue to be supported.
