GENERAL DESCRIPTION 

The 

ADP2119

/

ADP2120

 are synchronous, step-down, dc-to-dc 

regulators in a compact 3 mm × 3 mm LFCSP_WD package. 

The ADP2119/ADP2120 evaluation boards provide an easy way 
to evaluate the device. 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 2.3 V to 5.5 V 
and require minimal external components to provide a high 
efficiency solution with integrated power switch, synchronous 
rectifier, and internal compensation.
