Configuring the device
Note:
Note:
Output voltage is programmed through the VID pins: they are inputs of an internal DAC that
is realized by means of a series of resistors providing a partition of the internal voltage
reference. The VID code drives a multiplexer that selects a voltage on a precise point of the
divider. The DAC output is delivered to an amplifier obtaining the voltage reference (i.e. the
set-point of the error amplifier, VREF).
