ZL2106EVAL1Z Evaluation Board
Description
The ZL2106 is an innovative power conversion and
management IC that combines an integrated synchronous
step-down DC-DC converter with key power and fault
management functions in a small package, resulting in a
flexible and integrated solution. The ZL2106EVAL1Z platform
allows evaluation of the features in the highly configurable
ZL2106 in either stand-alone mode or via an I

C/SMBus™
interface.
A USB-to-SMBus reference board can be used to connect the
ZL2106EVAL1Z board to a PC. The PMBus command set is
accessed by using the PowerNavigator™ evaluation software
from a PC running Microsoft Windows.
