APPLICATION NOTE (CONTINU E D)
SOFT-START CAPACITOR
An external soft-start capacitor is connected to the
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.
PROGRAMMING THE OUTPUT VOLTAGE
Output voltage is determined by the internal 5 bit DAC.
The DAC inputs are the Voltage Identification (VID) 0-4
lines, the VID table lists the available output voltages for
the corresponding VID codes.
There are no external resistor dividers to program output
voltage and only the steps listed are available.
