4. ZL2006 Overview
4.1 Digital-DC Architecture
The ZL2006 is an innovative mixed-signal power
conversion 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.
Today’s embedded power systems are typically
designed for optimal efficiency at maximum load,
reducing the peak thermal stress by limiting the total
thermal dissipation inside the system. Unfortunately,
many of these systems are often operated at load levels
far below the peak where the power system has been
optimized, resulting in reduced efficiency. While this
may not cause thermal stress to occur, it does
contribute to higher electricity usage and results in
higher overall system operating costs.
Zilker Labs’ efficiency-adaptive ZL2006 DC-DC
controller helps mitigate this scenario by enabling the
power converter to automatically change their
operating state to increase efficiency and overall
performance with little or no user interaction needed.
Its unique PWM loop utilizes an ideal mix of analog
and digital blocks to enable precise control of the entire
power conversion process with no software required,
resulting in a very flexible device that is also very easy
to use. An extensive set of power management
functions are fully integrated and can be configured
using simple pin connections. The user configuration
can be saved in an internal non-volatile memory
(NVM). Additionally, all functions can be configured
and monitored via the SMBus hardware interface using

standard
flexibility.
Once enabled, the ZL2006 is immediately ready to
regulate power and perform power management tasks
with
configuration options and real-time configuration
changes are available via the I
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 3 V and 14 V with no
secondary bias supplies needed.
The ZL2006 can be configured by simply connecting
its pins according to the tables provided in the
following sections. Additionally, a comprehensive set
of online tools and application notes are available to
help simplify the design process. An evaluation board
is also available to help the user become familiar with
the device. This board can be evaluated as a standalone
platform
Windows™-based GUI is also provided to enable full
configuration and monitoring capability via the

the included USB cable.
Application notes and reference designs are available
to assist the user in designing to specific application
demands.
