10A Evaluation Board
ZL2005PEVK4 10A Evaluation Board
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 FG
ZL2005PEVK4 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 10A
configuration. It has been optimized for ease of
evaluation across a wide range of input and output
conditions. This FG ZL2005PEVK4 platform is provided
as a reference design.
