DACOUT pin and will be charged, or discharged, at a
linear rate by the internal 50uA bi-directional current source
after the UVLO circuit has been satisfied. Whenever the
VID code is changed during normal operation the soft-start
capacitor will determine the rate of change at the output.
OFT
An external soft-start capacitor is connected to the
