Description

The ZL9101EVAL1Z evaluation board provides all the circuitry required to evaluate the features of the ZL9101M digital DC/DC PMBus 12A module. The ZL9101EVAL1Z is a 6-layer board that provides a single-phase power rail up to 12A loads. The board is designed to efficiently transfer heat away from the module with passive cooling. A USB to SMBus adapter is used to connect the ZL9101EVAL1Z board to a PC. The PMBus command set is accessed by using the PowerNavigator evaluation software.

The ZL9101M is a 12A variable output, step-down power supply module. Included in the module is a high-performance digital PWM controller, power MOSFETs, an inductor, and all the passive components required for a complete DC/DC power solution. The ZL9101M operates over a wide input voltage range and supports an output voltage range of 0.6V to 4V, which can be set by external resistors or via the PMBus. This high-efficiency power module is capable of delivering 12A. Only bulk input and output capacitors are needed to finish the design. The output voltage can be precisely regulated to as low as 0.6V with ±1% output voltage regulation.
