ZL2102DEMO1Z
Demonstration Board
Description
The ZL2102DEMO1Z 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 small package, resulting in a flexible
and integrated solution. The ZL2102DEMO1Z platform allows
quick evaluation of the highly configurable ZL2102DEMO1Z's
performance and features in either stand-alone mode or via
the SMBus™ interface using Intersil's PowerNavigator GUI
software.
