Description
The DA9215 is a synchronous dual step-down converter supplying the processors core and GPU rail in smartphones, tablets, Ultrabooks, and other handheld applications requiring high currents. The DA9215 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 and standard 5V supply or USB power supplies. DA9215 delivers 15A and 5A output current, suitable for the highest performing application processors such as multicore arrangements of Arm® Cortex®-A15/A57 family. Due to the multiphase topology, DA9215 provides an outstanding ±2.5% load transient response and component sizes below 1mm height.
