The ZL2105 is an innovative mixed-signal power management and conversion IC that combines an integrated step-down DC/DC converter with key power and thermal management functions in a single package. The ZL2105EVK2 platform allows for the evaluation of the features in the highly configurable ZL2105 in either stand-alone mode or via an I2C/SMBus interface.

A USB-to-SMBus adapter board can be used to connect the ZL2105EVK2 board to a PC. The PMBus command set is accessed by using the PowerNavigator™ evaluation software from a PC running Microsoft Windows.
