Current reading and current sharing loop
L6714 embeds a flexible, fully-differential current sense circuitry that is able to read across
both low side or inductor parasitic resistance or across a sense resistor placed in series to
that element. The fully-differential current reading rejects noise and allows placing sensing
element in different locations without affecting the measurement's accuracy. The kind of
sense element can be simply chosen through the DAC/CS_SEL pin according to
See
Table 10
.
Current sharing control loop reported in
Figure 8
: it considers a current I

proportional to
the current delivered by each phase and the average current
between the read current I
INFOx
and the reference I
AVG
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
