Description
This document describes the characteristic and operation of the Qorvo ACT88422EVK1-101 evaluation kit (EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data. This EVK demonstrates the ACT88422-101 Qorvo PMU power management IC. Other ACT88422-xxx options can be evaluated on this EVK by replacing the IC and any other necessary components.
Features
The EVK can be used as a standalone board if desired. However, to access the internal registers and to takefull advantage of the IC’s capability, the user must connect the EVK kit to a PC with Qorvo’s USB-TO-I2Cinterface dongle and use the GUI software. The EVK provides full access to each converter’s input and outputvoltage, as well as all the digital control signals. This gives the user the flexibility to configure the EVK to matchtheir real-world system.
Typical applications
- Solid State Drives
- Portable Audio / Video
- Computer Vision
- FPGA
