ACT4910EVK1-121 User's Guide

Description

This document describes the characteristic and operation of the Active Semi ACT4910EVK1-121 evaluation kit

(EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data. This EVK

demonstrates the ACT4910QW121 eFuse power management IC. Other ACT4910QWxxx 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 ACT4910EVK1-121 is specifically configured for the

ACT4910QW121 IC.
