ZL2008
ZL2008 Overview
Digital-DC Architecture
The ZL2008 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 ZL2008 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 PMBus
commands, allowing ultimate flexibility.
Once enabled, the ZL2008 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
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.
