ADP5301-EVALZ: 1.8V @ 50mA / 500mA, 2.15 ~ 6.5V in

Summary

The ADP5301 is an ultralow power, synchronous, step-down dc-to-dc regulator with a load switch in a 9-ball WLFCSP package. The ADP5301 runs from input voltages of 2.15 V to 6.50 V and requires minimal external components to provide a high efficiency solution with integrated power switch, synchronous rectifier, and internal compensation.

The ADP5301-EVALZ 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 ADP5301 is available in the ADP5301 data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
