NOTES:
4. When using the internal shunt regulator, VCC is clamped to 6.02V (max). Current must be limited to 25mA or less.
5. These parts are designed and adjusted for accuracy with all errors in the voltage loop included.
6. During soft-start, VDAC rises from 0 to VID. The overvoltage trip level is the higher of 1.7V and VDAC + 0.2V.
