VFB is 0.6V when the part ist powered up and no DVS is changed. DVS is achieved by modifying VFB reference.

Table 4. Static Electrical Characteristics (continued)

Characteristics noted under conditions 2.7 V

≤ VIN ≤ 5.5 V, -20°C ≤ TA ≤ 85°C, GND = 0 V, unless otherwise noted. Typical

values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.
