MAX5960L Hardware Only Configuration

1)

Verify that shunts are installed on jumpers JU1,

JU2, JU3, and JU4 (

PRES-DET_).

2)

Verify that shunts are installed on pins 1 and 2 of

jumpers JU5, JU6, JU7, JU8, JU11, JU12, JU13,

and JU14 (local switch control).

3)

Verify that a shunt is not installed on jumpers JU9,

JU10, JU15, and JU16 (MRL_).

4)

Utilizing short 25A-rated banana leads (< 12in

long) connect the 12V DC power supply to the

VIN1 banana jack. Utilizing short 25A-rated banana

leads (< 12in long) connect the supply ground to

the GND banana jack.

5)

Utilizing short 25A-rated banana leads (< 12in

long) connect the 3.3V DC power supply to the

VIN2 banana jack. Utilizing short 25A-rated banana

leads (< 12in long) connect the supply ground to

the GND banana jack.

6)

Connect the 3.3V DC power supply to the VIN3

banana jack with a short banana lead.

7)

Connect a voltmeter to the 12VA pad and GND.

Connect a voltmeter to the 3.3VA pad and GND.

Connect a voltmeter to the 3.3VAUXA pad and GND.

8)

Set switches SW5, SW7, SW9, SW11 (ON_), and

SW6, SW8, SW10, SW12 (AUXON_) to the OFF

position.

9)

Turn on both power supplies in any sequence.

10) Set switches SW5 (ONA) and SW6 (AUXONA) to

the ON position.

11) Verify that the voltage at channel A pad is as

shown below:

12VA = 12V

3.3VA = 3.3V

3.3VAUXA = 3.3V

12) Sliding switches SW5 and SW6 to the OFF position

will disable the channel A main or auxiliary outputs

on the MAX5960L EV kit.

13) For evaluating channels B, C, and D, use analo-

gous actions on steps 10 through 12 above for the

respective channel switch setting and output volt-

age reading. See the

Jumper and Switch Selection

section for more information on configuring the

respective channel.

14) Test points are provided to observe the MOSFET’s

gate voltage respectively with an oscilloscope.

Software and Hardware Quick Start

The MAX5960L EV kit is fully assembled and tested.

Follow these steps to verify board operation. Do not

turn on the power supplies until all connections are

completed.

MAX5960L Software and Hardware Configuration

1)

Visit www.maxim-ic.com/evkitsoftware to download

the latest version of the EV kit software,

5960LRxx.ZIP. Save the EV kit software to a tempo-

rary folder and uncompress the ZIP file.

2)

Install the EV kit software on your computer by run-

ning the INSTALL.EXE program inside the temporary

folder. The program files are copied and icons are

created in the Windows Start | Programs menu.

3)

Verify that no shunts are installed on jumpers JU1,

JU2, JU3, and JU4 (

PRES-DET_).

4)

Verify that shunts are installed on pins 2 and 3 of

jumpers JU5, JU6, JU7, JU8, JU11, JU12, JU13,

and JU14 (computer control).

5)

Verify that a shunt is not installed on jumpers JU9,

JU10, JU15, and JU16 (MRL_).

6)

Utilizing short 25A-rated banana leads (< 12in

long) connect the 12V DC power supply to the

VIN1 banana jack. Utilizing short 25A-rated banana

leads (< 12in long) connect the supply ground to

the GND banana jack.

7)

Utilizing short 25A-rated banana leads (< 12in

long) connect the 3.3V DC power supply to the

VIN2 banana jack. Utilizing short 25A-rated banana

leads (< 12in long) connect the supply ground to

the GND banana jack.

8)

Connect the 3.3V DC power supply to the VIN3

banana jack with a short banana lead. Do not turn

on the power supplies.
