Upon system start-up, the device with the lowest member
position as selected in ISHARE_CONFIG is defined as the
reference device. The remaining devices are members. The
TABLE 28. CURRENT SHARE PIN-STRAP SETTINGS
reference device broadcasts its current over the DDC bus. The
members use the reference current information to trim their
voltages (V MEMBER ) to balance the current loading of each device
in the system.
Figure 18 shows that, for load lines with identical slopes, the
member voltage is increased towards the reference voltage

which closes the gap between the inductor currents.
The relation between reference and member current and voltage
TABLE 29. CURRENT SHARE RESISTOR SETTINGS
is given by Equation 37:
V MEMBER = V OUT + R × ( I REFERENCE ? I MEMBER )

for active current sharing. The default setting is a stand-alone
non-current sharing device. A current sharing rail can be part of a
system sequencing group.
For fault configuration, the current share rail is configured in a
quasi-redundant mode. In this mode, when a member device
fails, the remaining members will continue to operate and
attempt to maintain regulation. Of the remaining devices, the
device with the lowest member position will become the
reference. If fault spreading is enabled, the current share rail
failure is not broadcast until the entire current share rail fails.
When Auto Compensation is enabled, only two (2) devices can be
configured for current sharing. With Auto Compensation
disabled, up to eight (8) devices can be configured in a given
current sharing rail.
