Overview

Description

DA9214 is a synchronous dual step down converter supplying the processors core and GPU rail in smartphones, tablets, Ultrabooks™ and other handhelds applications requiring high currents. DA9214 is also suitable for powering FPGA’s.

The input voltage range of 2.8 to 5.5V makes it suitable for the use of single cell Lithium-Ion battery applications as well as standard 5V supply or USB power supplies. DA9214 delivers 2x 10A output current, suitable for the highest performing application processors such as multi core arrangements of ARM Cortex A15/A57 family. Due to the multiphase topology DA9214 provides outstanding load transient response and component sizes below 1mm height.
