ACT86600EVK1-101 User’s Guide

 

Description

This document describes the characteristics and operation of  the Qorvo ACT86600EVK1-101 evaluation kit 
(EVK).  It  provides  setup  and  operation  instructions,  schematic,  layout,  BOM,  and  test  data.  This  EVK 
demonstrates the ACT86600QM101 ActivePMU power management IC. Other ACT86600QMxxx 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 take 
full  advantage  of  the  IC’s  capability,  the  user  must  connect  the  EVK  kit  to  a  PC  with  Qorvo’s  USB-TO-I2C 
interface dongle and use the GUI software. The EVK provides full access to the each converter’s input and 
output voltage, as well as all the digital control signals. This gives the user the flexibility to configure the EVK 
to match their real-world system. 

Note that the ACT86600EVK1-101 is specifically configured for the ACT86600QM101.
