SEQUENCING CONFIGURATION
Seguencing is disabled
The ZL6100 is configured as the first device in a nested
sequencing group. Turn on order is based on the device SMBus
address.
The ZL6100 is configured as a last device in a nested
sequencing group. Turn on order is based on the device SMBus
address.
The ZL6100 is configured as the middle device in a nested
sequencing group. Turn on order is based on the device SMBus
address.
Droop resistance is used to add artificial resistance in the
The relation between reference and member current and
output voltage path to control the slope of the load line curve,
calibrating out the physical parasitic mismatches due to
power train components and PCB layout.
voltage is given by using Equation 41:
V member = V OUT + R × ( I REFERENCE ? I MEMBER )
(EQ. 41)
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
reference device broadcasts its current over the DDC bus.
The members use the reference current information to trim
their voltages (VMEMBER) to balance the current loading of
each device in the system .

where R is the value of the droop resistance.
The ISHARE_CONFIG command is used to configure the
device 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.
Up to eight (8) devices can be configured in a given current
sharing rail. The maximum current for a current sharing rail
is limited by the droop and number of phases. Refer to
Application Note AN2034 “Current Sharing with Digital-DC?
Devices” for complete details on current sharing.

member voltage is increased towards the reference voltage
which closes the gap between the inductor currents.

connected in parallel to supply higher load currents than can
be addressed using a single-phase design. In doing so, the
power converter is optimized at a load current range that
requires all phases to be operational. During periods of light
loading, it may be beneficial to disable one or more phases
in order to eliminate the current drain and switching losses
associated with those phases, resulting in higher efficiency.
