ADP5303-EVALZ: 1.8V @ 500mA, 2.15 ~ 6.5V in, Buck

Summary

The ADP5303 is an ultralow power, synchronous step-down dc-to-dc regulator in a 9-lead WLCSP package. The ADP5303 runs from input voltages of 2.06 V to 6.5 V and requires minimal external components to provide a high efficiency solution with an integrated power switch, synchronous rectifier, and internal compensation.

The ADP5303 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 ADP5303 is available in the ADP5303 data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
