ISL6244EVAL1 Multi-phase Evaluation Board

Setup Procedure

This document describes the setup procedure for the
ISL6244EVAL1 Rev B board for AMD Mobile K8 Processors.

Description

The AMD Hammer family microprocessors feature higher
clock speeds and greater device density than previous
product families. The power management solution for this
next generation family of microprocessors must contend with
lower core voltages, tighter transient specifications, and
higher peak current demands. Responding to the changing
power management needs of its customers, Intersil
introduces the ISL6244 controller to power the AMD
Hammer family microprocessors.

Intersil ISL6244 and ISL6207

The ISL6244EVAL1 Rev B is a versatile voltage regulator-
down (VRD) design. The evaluation board comes configured
for 3-phase multi-phase buck operation, designed to meet
AMD Hammer Family Desktop Processor specifications. The
board layout supports removal or addition of the third and
fourth phases to support multiple applications. The ISL6244
controller features are specifically designed to compliment
and support the Hammer Family processors. Interfaced with
ISL6207 drivers, the chipset forms a highly integrated
solution for AMD Hammer processor applications.

The ISL6244 regulates output voltage and balances load
currents for two to four synchronous buck converter
channels. The controller features a 5-bit DAC which provides
a digital interface for accurate step down conversion over
the entire Hammer Family range of 0.800V to 1.550V. New
multi-phase family features include differential remote output
voltage sensing to improve regulation tolerance, pin-
adjustable reference offset for ease of implementation, VID-
on-the-Fly to respond to DAC changes during operation, and
optional load line regulation. For a more detailed description
of the ISL6244 functionality, refer to the data sheet [1].

The ISL6207 driver is chosen to drive two N-Channel power
MOSFETs in a synchronous-rectified buck converter
channel. Each channel has a single logic input which
controls the upper and lower MOSFETs. Dead time is
optimized on both switching edges to provide shoot-thru
protection. Internal bootstrap circuitry only requires an
external capacitor and provides better enhancement of the
upper MOSFET. For a more detailed description of the
ISL6207, refer to the data sheet [1].

The Intersil multi-phase family driver portfolio continues to
expand with new selections to better fit our customer's
needs.

What's Inside

The Evaluation Board Kit contains the following materials:

· The ISL6244 EVAL Board

· The ISL6244 Evaluation Board document

What is Needed

The following materials will be needed to perform testing:

· 1 to 2 electronic loads [see note]

0-25V @ 15A (+VDC)
0-5V @ 5A (+5V)
0-12V @ 1A (+12V)

· precision digital multi-meters

NOTE: amperage rating of power supplies are determined by
maximum expected loading plus a percentage margin of error

Quick Setup Guide

Step 1:

Set the 0-5V power supply to +5V and place in the
"STANDBY" or "OFF" position. Connect the
positive terminal (+) of the supply to the +5V
terminal J5 and the negative terminal (-) of the
supply to GND J7.

Step 2:

Connect the positive terminal (+) of a DMM to the
+5V terminal J5 and the negative terminal (-) to the
GND terminal J7.

Step 3:

Set the +VDC power supply to +19V and place in
the "STANDBY" or "OFF" position. Connect the
positive terminal (+) of the supply to the +VDC
terminal J3 and the negative terminal (-) of the
supply to GND J4.Connect the load

Step 4:

Connect the positive terminal (+) of a DMM to the
+VDC terminal J3 and the negative terminal (-) to
the GND terminal J4.

Step 5:

Set the 0-12V power supply to +12V and place in
the "STANDBY" or "OFF" position. Connect the
positive terminal (+) of the supply to the +12V
terminal J6 and the negative terminal (-) of the
supply to GND J8.

Step 6:

Connect the positive terminal (+) of a DMM to the
+5V terminal J5 and the negative terminal (-) to the
GND terminal J7.

Step 7:

Connect the positive terminal (+) of the electronic
load to the VOUT terminal J1. Connect the
negative terminal (-) of the electronic load to the
GND terminal J2. Make sure the electronic load is
set to the 0A condition.

Step 8:

Connect the positive terminal (+) of a DMM to the
VOUT test point TP13 and the negative terminal (-)
to the GND test point TP14.

Step 9:

Check to ensure all jumpers and switches are in
their default positions prior to application of power
(refer to"Detailed Description of Jumper Settings"
and "Detailed Description of Switch Settings" ).

Step 10: Set all power supplies to the "ON" position. LED

CR1 should show Red. Check all DMM displays for
correct voltage levels. Adjust if necessary.

Step 11: Turn the ENABLE switch SW2 to the "ON" position.

LED CR1 should show Green. The VOUT DMM
should read 1.60V (

1%).

At this point the board has been properly powered up.
Normal testing can begin.
