Adaptive Digital DC/DC Controller with
Features
Drivers and Current Sharing
Power Conversion
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.
• Efficient Synchronous Buck Controller
• Adaptive Light Load Efficiency Optimization
• 3V to 14V Input Range
• 0.54V to 5.5V Output Range (with Margin)
• ±1% Output Voltage Accuracy
• Internal 3A MOSFET Drivers
• Fast Load Transient Response
• Current Sharing and Phase Interleaving
• Snapshot™ Parameter Capture
• 36 Ld 6mmx6mm QFN Package
• Pb-Free (RoHS Compliant)
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.
Power Management
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.
• Digital Soft-start/stop
• Precision Delay and Ramp-up
• Power-Good/Enable
• Voltage Tracking, Sequencing and Margining
• Voltage/Current/Temperature Monitoring
• I2C/SMBus Interface (PMBus Compatible)
• Output Voltage and Current Protection
• Internal Non-volatile Memory (NVM)

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.
