描述
The DA9213-A is a synchronous 20A step-down converter supplying the processor's core or GPU rail in automotive infotainment and navigation system applications requiring high currents. DA9213-A is also suitable for powering FPGAs.
The input voltage range of 2.8V to 5.5V makes it suitable for standard 5V supplies or USB power supplies. DA9213-A delivers 20A of output current, suitable for the highest performing application processors such as multicore arrangements of the Arm® Cortex®-A15/A57 family. Due to the multiphase topology, DA9213-A provides outstanding ±2% load transient response and component sizes below 1mm height.
