Adaptive Digital DC/DC Controller with
Drivers and Current Sharing
ZL6100 is a digital power 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.

NOTES:
1. Add “T*” suffix for tape and reel. Please refer to TB347 for details
on reel specifications.
2. 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.
3. For Moisture Sensitivity Level (MSL), please see device
information page for ZL6100. For more information on
MSL, please see Technical Brief TB363.
4. Only for customers that do not want to order new
firmware.
