Overview

Description

The DA9083 is a six-channel system power management IC that integrates four buck converters, one LDO, and one load switch. This high current, integrated PMIC is ideal for Client and Enterprise SSD Modules, Hybrid Drives, and other memory management applications. Due to its highly configurable and flexible design, it supports a wide variety of other applications with integrated microcontrollers, DSPs, and FPGAs in embedded applications and a host of other Internet of Things (IoT) and consumer applications. The DA9083 is offered in a 36 WLCSP package.
