The ADP2164 is a synchronous, step-down dc-to-dc regulator in a compact, 4 mm × 4 mm LFCSP package. The ADP2164 requires minimal external components to provide a high efficiency solution with integrated power switch, synchronous rectifier, and internal compensation. The input voltage range of the ADP2164 is 2.7 V to 6.5 V. The ADP2164 evaluation board provides an easy way to evaluate the device. This user guide describes how to quickly set up the board to collect performance data. Complete information about the ADP2164 is available in the ADP2164 data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
