ADP2120-EVALZ: 1.2V @ 1.25A, 2.3 ~ 5.5V in


The ADP2119/ADP2120 evaluation boards provide an easy way to evaluate the synchronous, step-down devices. This user guide describes how to quickly set up the board to collect performance data. Full details on the ADP2119/ADP2120 are available in the ADP2119/ADP2120 data sheet, which is available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using the evaluation boards.

The ADP2119/ADP2120 run from input voltages of 2.3V to 5.5V and require minimal external components to provide a high efficiency solution with integrated power switch, synchronous rectifier, and internal compensation.
