ADP5055-EVALZ

ADP5055-EVALZ is a full-featured evaluation board for the ADP5055 triple buck regulator integrated power solution. The ADP5055 combines three high-performance buck regulators in a 43-terminal land grid array (LGA) to meet the demanding performance and board space requirements. The ADP5055-EVALZ connects to input voltages up to 18V directly, without any preregulators. The ADP5055 includes a PMBus®-compatible serial interface and the ADP5055-EVALZ can be used with an external USB dongle and graphical user interface (GUI) software to evaluate the power management functionalities and to read back system status.
