FN6876.1
Adaptive Digital DC/DC Controller with
Drivers and Current Sharing
Features
The ZL6100 is a digital DC/DC controller with integrated
MOSFET drivers. Current sharing allows multiple devices to
be connected in parallel to source loads with very high
current demands. Adaptive performance optimization
algorithms improve power conversion efficiency across the
entire load range. Zilker Labs Digital-DC™ technology
enables a blend of power conversion performance and
power management features.
The ZL6100 is designed to be a flexible building block for DC
power and can be easily adapted to designs ranging from a
single-phase power supply operating from a 3.3V input to a
multi-phase supply operating from a 12V input. The ZL6100
eliminates the need for complicated power supply managers
as well as numerous external discrete components.
All operating features can be configured by simple
pin-strap/resistor selection or through the SMBus™ serial
interface. The ZL6100 uses the PMBus™ protocol for
communication with a host controller and the Digital-DC bus
for communication between other Zilker Labs devices.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
