Overview

Description

The DA9214 is a synchronous dual step-down converter supplying the processor core and GPU rail in smartphones, tablets, Ultrabooks™, and other handheld applications requiring high currents. DA9214 is also suitable for powering FPGAs.

The input voltage range of 2.8V 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 the multi-core arrangements of the Arm® Cortex®-A15/A57 family. Due to the multiphase topology, DA9214 provides outstanding load transient response and component sizes below 1mm height.
