ZL2004
4. ZL2004 Overview
4.1 Digital-DC Architecture
The ZL2004 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 ZL2004 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 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
pin connections or via the I 2 C/SMBus hardware
interface using standard PMBus commands. The user
configuration can be saved in an on-chip non-volatile
memory (NVM), allowing ultimate flexibility.

Once enabled, the ZL2004 is immediately ready to
regulate power and perform power management tasks
with no programming required. The ZL2004 can be
configured by simply connecting its pins according to
the tables provided in this document. Advanced
configuration options and real-time configuration
changes are available via the I 2 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 4.5 V and 14 V with no
secondary bias supplies needed.
Zilker Labs provides a comprehensive set of
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. Additionally, a Windows? -
based GUI is provided to enable full configuration and
monitoring capability via the I 2 C/SMBus interface
using an available computer and the included USB
cable.

most up-to-date documentation or call your local Zilker
Labs’ sales off ice to order an evaluation kit.
