Description

The ZL2006 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 ZL2006 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 3.3 V input to a multi-phase supply operating

from a 12 V input. The ZL2006 eliminates the need for

complicated power supply managers as well as

numerous external discrete components.

All operating features can be configured by simple pinstrap/resistor selection or through the SMBus™ serial

interface. The ZL2006 uses the PMBus™ protocol for

communication with a host controller and the DigitalDC bus for communication between other Zilker Labs

devices.
