ACT88325EVK1-101 User’s Guide
Description
This document describes the characteristic and operation of the Active Semi ACT88325EVK1-101 evaluation
kit (EVK).It provides setup and operation instructions, schematic, layout, BOM, and test data. This EVK
demonstrates the ACT88325VA101ActivePMU power management IC. Other ACT88325VAxxx 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 Active Semi’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 ACT88325EVK1-101 is specifically configured for the ACT88325VA101. This CMI option is
configured to power the Silicon Motion 2263 and SM2263XT processors with a 3.3V input.
