CORE Voltage Programming

The voltage identification pins (VID0, VID1, VID3, and VID4)

set the CORE output voltage. Each VID pin is pulled to 2.5V by

an internal 20µA current source and accepts open-collector/

open-drain/open-switch-to-ground or standard low-voltage

TTL or CMOS signals.

Table 1 shows the nominal DAC voltage as a function of the

VID codes. The power supply system is ±0.8% accurate over

the operating temperature and voltage range.
