3. These parts are designed and adjusted for accuracy with all errors in the voltage loop included.
4. Spec guaranteed by design.
5. During soft-start, VDAC rises from 0 to 1.1V first and then ramp to VID voltage after receiving valid VID input.
6. Soft-start ramp rate is determined by the adjustable soft-start oscillator frequency at the speed of 6.25mV per cycle.
