説明
The DA9214-A is a synchronous dual step-down converter supplying the processor's core and GPU rail in automotive infotainment and navigation system applications requiring high currents. DA9214-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. DA9214-A delivers2x 10A 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, DA9214-A provides outstanding load transient response and component sizes below 1mm height.
