Digital DC/DC Controller with Drivers and Pin-Strap
Current Sharing
ZL2008
The ZL2008 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. Zilker Labs Digital-DC?
technology enables a blend of power conversion performance
and power management features.
The ZL2008 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 ZL2008
eliminates the need for complicated power supply managers
as well as numerous external discrete components.
Key operating features can be configured by pin-straps,
including compensation, current sharing and output voltage.
The ZL2008 uses the I 2 C/SMBus? with PMBus? protocol for
communication with a host controller and the Digital-DC bus
for communication between Zilker Labs devices.
Applications
? Servers/storage equipment
? Telecom/datacom equipment
? Power supply modules
