Current reading and current sharing loop
33/64
The Rg trans-conductance resistor has to be selected using the following formula, in order
to guarantee the correct functionality of internal current reading circuitry:
Current sharing control loop reported in Figure 9: it considers a current IINFOx proportional to
the current delivered by each phase and the average current
. The error
between the read current IINFOx and the reference IAVG is then converted into a voltage that
with a proper gain is used to adjust the duty cycle whose dominant value is set by the
voltage error amplifier in order to equalize the current carried by each phase. Details about
connections are shown in Figure 8.
