Adaptive Digital DC-DC Controller with Current Sharing
Description
The ZL2004 is a digital DC-DC controller designed to
work with the ZL1505 MOSFET driver IC. 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 ZL2004 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 4.5 V input to a multi-phase supply operating
from a 12V input. The ZL2004 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 selectio n or through the SMBus? serial
interface. The ZL2004 uses the PMBus? protocol for
communication with a host controller and the Digital-
DC bus for communication between other Zilker Labs
devices.
