ZL2101
ZL2101 Overview
Digital-DC Architecture
The ZL2101 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 ZL2101
integrates all necessary PWM control circuitry as well as low
r DS(ON) synchronous power MOSFETs to provide an extremely
small solution for supplying load currents up to 6A.
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 ZL2101 is immediately ready to regulate
power and perform power management tasks with no
The ZL2101 can be configured by simply connecting its pins
according to the tables provided in the following sections.
Additionally, a comprehensive set of 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.
Power Conversion Overview
The ZL2101 operates as a voltage-mode, synchronous buck
converter with a selectable constant frequency pulse width
modulator (PWM) control scheme. The ZL2101 integrates dual low
r DS(ON) synchronous MOSFETs to minimize the circuit footprint.
Figure 10 illustrates the basic synchronous buck converter
topology showing the primary power train components. This
converter is also called a step-down converter, as the output
voltage must always be lower than the input voltage.

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 external supply between 4.5V and 14V
with no secondary bias supplies needed. The ZL2101 can also be

configured to operate from a 3.3V or 5V 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.
