Setup Instructions for the ISL6271A Evaluation Kit

Dynamic Voltage Management(DVM)

via I2C

The following steps will guide the evaluator through

the set-up required to control both the voltage level

and slew rate of Vcore dynamically from a PC over a

USB-to-I2C interface. The user will be able to easily

set the core voltage at any one of 16 discrete levels

between 0.85V and 1.3V, and the slew rate to one of

4 discrete levels from .1mV/uS to 5mV/uS (see data

sheet) simply by selecting the desired level(s) and

commanding a ‘writeI2C’ to the device.

Load Driver Software

The first step is to connect the USB-I2C interface

module to the PC USB port with the supplied cable

(Figure 10) .

Next install the driver software for the I2C interface,

provided on the same evaluation kit CD as this

document (see Appendix B), and by following the

installation instructions provided in Appendix B.

The screen below will appear after the application

software is installed and the testing application is

executed.

Hardware Module(s) Interconnect

Once the SW is loaded and the DVM-choice screen is displayed (Figure 11), the two boards should be connected

together ( Figure 12). Before connecting the cable between the eval board and the USB-I2C module (Figure 2),

apply input power (3.7V) to the eval board and then connect the interconnecting cable to J2 on the eval board.

Switch S1 position 6 should be switched to the ‘right’ for I2C testing.
