ZL2005 Overview
4.1 Digital-DC Architecture
The ZL2005 is an innovative mixed-signal power con-
version and power management IC based on Zilker
Labs’ patented Digital-DC technology that provides
an integrated, high performance step-down converter
for a wide variety of power supply applications. Its
unique digital PWM loop utilizes an innovative
mixed-signal topology to enable precise control of the
power conversion process with no software required,
resulting in a very flexible device that is also easy to
use. An extensive set of power management functions
is fully integrated and can be configured using simple
2
pin connections or via the I
C/SMBus hardware inter-
face using standard PMBus commands. The user con-
figuration can be saved in an on-chip non-volatile
memory (NVM), allowing ultimate flexibility.
Once enabled, the ZL2005 is immediately ready to
regulate power and perform power management tasks
with no programming required. The ZL2005 can be
configured by simply connecting its pins according to
the tables provided in this document. Advanced con-
figuration options and real-time configuration changes
2
are available via the I
C/SMBus interface if desired,
and continuous monitoring of multiple operating
parameters is possible with minimal interaction from a
host controller. Integrated sub-regulation circuitry
enables single supply operation from any supply
between 3V and 14V with no secondary bias supplies
needed.
Zilker Labs provides a comprehensive set of on-line
tools and application notes to assist with power supply
design and simulation. An evaluation board is also
available to help the user become familiar with the
device. This board can be evaluated as a stand-alone
platform using pin configuration settings. Addition-
ally, a Windows™-based GUI is provided to enable
full configuration and monitoring capability via the
2
I
C/SMBus interface using an available computer and
the included USB cable.
