ZL6100EVAL2Z Dual Channel Evaluation Board
Description
The ZL6100 is an integrated mixed-signal power
conversion and management IC that combines an
efficient step-down DC/DC converter with key power and
thermal management functions in a single package. The
ZL6100 incorporates current sharing and adaptive
efficiency-optimization algorithms to provide a flexible,
efficient power IC building block.
The ZL6100EVAL2Z platform is a 6-layer board with two
power rails. One rail is a single phase, 30A power rail.
The other rail is a dual phase, 60A power rail
demonstrating the current sharing capability of the
ZL6100.
A USB to SMBus adapter board can be used to connect
the eval board to a PC. The PMBus command set is
accessed by using the Zilker Labs PowerNavigator™
evaluation software from a PC running Microsoft
Windows.
