Overview

Product Details

This describes the design, operation, and test results of the ADP1850DP-EVALZ operating in dual-phase mode and the ADP1850SP-EVALZ operating in single-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.


The input range for the ADP1850SP-EVALZ evaluation board is 10 V to 20 V, and the two regulated output voltages are set to 3.3 V (VOUT1) and 1.8 V (VOUT2) with a maximum 14 A output current. A switching frequency (fSW) of 600 kHz is chosen to achieve a good balance between efficiency and the sizes of the power components.
