ZL2105
4. ZL2105 Overview
4.1 Digital-DC Architecture
The ZL2105 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
point of load applications. The ZL2105 integrates all
necessary PWM control circuitry as well as
synchronous 4.5 A N-channel MOSFETs in order to
provide an extremely small solution for providing load
currents up to 3 A. 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 PMBus commands, allowing
ultimate flexibility.
Once enabled, the ZL2105 is immediately ready to
regulate power and perform power management tasks
with no programming required. Advanced
configuration options and real-time configuration
changes are available via the I 2 C/SMBus interface if
desired and continuous monitoring of multiple
can also be configured to operate from a 3.3 V or 5 V
standby supply when the main power rail is not
present, allowing the user to configure and/or read
diagnostic information from the device when the main
power has been interrupted or is disabled.
The ZL2105 can be configured by simply connecting
its pins according to the tables provided in the
following sections. Additionally, a comprehensive set
of 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 using pin configuration settings. A
Windows ? -based GUI is also provided to enable full
configuration and monitoring capability via the
I 2 C/SMBus interface using an available computer and
the included USB cable.
Application notes and reference designs are available
to assist the user in designing to specific application
demands. Please register for My ZL on

date documentation or call your local Zilker Labs sales
office to order an evaluation kit.
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
