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.

Page 3: Quick Start
Quick Start Hardware Setup 1. Decide which voltage will power VIO. Qorvo recommends powering VIO from the VCC5 output for general evaluation. Install a shorting jumper between J1-1 and J1-2 to power VIO from VCC5. Or use a wire to connect J1-2 to any Buck converter output. - Page 4 Refer to Figure 4 to ensure the correct polarity of the connection. As a guide, use the “Qorvo” logo (or “Active-Semi” logo) on the top of the dongle so the black wire is connected to the Dongle GND pin.

Page 5: Sleep Mode
Enter Sleep Mode by changing voltage level of GPIO4 from low to high. In Sleep Mode, the BUCK1/2/3 are still on, meanwhile BUCK4 and BUCK-BOOST outputs turn off. This is the default EVK sleep setting. However the sleep/deep sleep settings are configurable.
