ADP5034-1-EVALZ: 2x 1V @ 1A Buck, 2x 1V @ 300mA LDO, 2.3 ~ 5.5V

Summary

This user guide describes the hardware for the evaluation of the ADP5023/ADP5024/ADP5034/ADP5037 and includes detailed schematics and PCB layouts. The ADP5023/ADP5024/ ADP5034/ADP5037 are available in a 24-lead 4 mm × 4 mm LFCSP package. The ADP5023/ADP5024 are three-channel devices that share a common PCB evaluation board. The ADP5034/ADP5037 are four-channel devices and share a common evaluation board. The ADP5023/ADP5024/ADP5034 and ADP5037 all operate in the same manner. Note that this user guide covers all of these boards, but refers to the ADP5034 for simplicity.

The ADP5034 LFCSP evaluation board has two step-down regulators with two LDOs that enable evaluation of the ADP5034. The evaluation board is available in an adjustable voltage option.

Full details on the parts are provided in the appropriate product data sheet available from Analog Devices, Inc., which should be consulted in conjunction with this evaluation board user guide.
