dynamic control of DC/DC converters
We can drive LTM_VPWR1_CTR in range 0-4V, which translates to ~3.3V on LTM1_VFB1 (maximum rating is 2.7V). Moreover, DC/DC converter enforces on this node 0.8V. Maybe it would be better to use digital potentiometer powered by some LDO powered further by the fixed voltage LTM_VCC5?
