ADP5050-EVALZ: 5 Ch., 4.5 ~ 15V in, Buck/LDO

Summary

This user guide describes the hardware and software for the evaluation of the ADP5050/ADP5052 and includes detailed schematics and printed circuit board (PCB) layouts.

The ADP5050/ADP5052 evaluation board combines four high performance buck regulators and one 200 mA LDO in a 48-lead LFCSP package to meet the demanding performance and board space requirements. The ADP5050/ADP5052 evaluation board can connect to high input voltages, up to 15 V directly without any pre-regulators.

The ADP5050/ADP5052 share a common PCB evaluation board. The ADP5050/ADP5052 board can support an external USB dongle connection and the GUI software to evaluate the comprehensive functionalities provided by I2C interface, whereas the ADP5052 has no I2C interface capability. Both the ADP5050 and the ADP5052 operate in the same manner and are available in an adjustable voltage option.

Full details on the devices are provided in the ADP5050/ADP5052 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with this evaluation board user guide.
