Description
The ZL2005P is an innovative mixed-signal
power management and conversion IC that
combines a compact, efficient, synchronous buck
controller, adaptive drivers and key power and
thermal management functions in a single
package. The ZL2005PEV4 platform allows
evaluation of the features in the highly-
configurable ZL2005P via the SMBus interface
using PMBus
™
commands. The PMBus
command set is accessed by using Zilker Labs
evaluation software from a PC running Microsoft
Windows.
This evaluation board is meant to enable rapid
evaluation of the functionality of the ZL2005P in
a 10 Amp configuration. It has been optimized for
ease of evaluation across a wide range of input
and output conditions.
This ZL2005PEV4
platform is provided as a reference design.
