Evaluation Board for the ADP1850DP Step-Down DC-to-DC Controller


TopologyBuck Converter
Input voltage10-15 V
Output 11.09 V / 50 A
IC revisionA


This document describes the design, operation, and test results of the ADP1850DP-EVALZ operating in dual-phase mode. The input range for this evaluation board is 10 V to 15 V, and the regulated output voltage is 1.09 V with a maximum 50 A output current. A switching frequency (fSW) of 300 kHz is chosen to achieve a good balance between efficiency and the sizes of the power components.
