DESCRIPTION

LTC3884 UK Package Programming board for Dual Output PolyPhase

DC/DC Controller with Digital Power Management

Demonstration circuit 2298A contains the circuitry needed to program and verify the EEPROM of the LTC3884 in the UK package and that is its only purpose. The DC2298A is shipped with a LTC3884 installed in the clamshell style programming socket and its EEPROM contains the factory default configuration. The LTpowerPlay® #.proj file that corresponds to the factory default can be found in the GUI.

In order to properly verify the contents of the EEPROM, download and install the LTpowerPlay software (GUI). The software can be downloaded from:

http://www.linear.com/ltpowerplay

You also need a Linear Technology USB to I2C/SMBus/PMBus dongle, DC1613A or DC1427A.

DEMO SYSTEM REQUIRED HARDWARE n Windows PC n USB to I2C/SMBus/PMBus Controller, DC1613A or

DC1427A n DC2298A

DEMO SYSTEM REQUIRED SOFTWARE n LTpowerPlay

L, LT, LTC, LTM, LTpowerPlay, PolyPhase, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners.

LTC3884 FEATURES n PMBus/I2C compliant serial interface n Sub-milliohm DCR current sensing n Telemetry read back includes VIN, IIN, VOUT, IOUT,

temperature and faults n Programmable voltage, current limit, digital soft-start/

stop, sequencing, margining, control loop compen-sation, OV/UV/OC and frequency synchronization (200kHz to 1MHz)

n ±0.5% output voltage accuracy over temperature n Internal EEPROM and fault logging n Integrated powerful N-channel MOSFET gate drivers n Wide VIN range: 4.5V to 38V n VOUT range: 0.5V to 3.5V (with low DCR setting);

0.5V to 5.5V (without low DCR setting) n Accurate PolyPhase® current sharing for up to 6 phases n Available in a 48-lead (7mm × 7mm) QFN Package

Design files for this circuit board are available at http://www.linear.com/demo/DC2298A

DEMO MANUAL DC2298A

QUICK START PROCEDUREDemonstration circuit 2298A makes it easy to program and verify the EEPROM contents of the LTC3884 in the UK package.

1. Make sure jumpers are in the following positions:

JUMPER POSITION FUNCTION

JP1 DISABLE Write Protection of LTC3884

JP2 ENABLE Write Protection of Identification EEPROM

2. Open the lid of the socket. Verify there is an IC inside. See Figure 2.

3. Close the lid. It will snap into place.

NOTE. Removal and insertion of the IC should be done with either a tweezers or a vacuum suction device.

4. Plug one end of the USB cable to your PC. Plug other end of USB cable into the I2C/SMBus/PMBus dongle.

5. If you have a DC1427A, plug the ribbon cable into J1. If you have a DC1613A, plug the ribbon cable into J2. See Figure 3.

6. On your PC, launch LTpowerPlay. LTpowerPlay will identify the DC2298A and launch the appropriate GUI. See Figure 4.

NOTE. You will see an Under Temperature (UT) Fault. This is normal since the temperature sensing pin is grounded. Ignore this fault at the moment.

7. Change the GUI parameters according to your system requirements. Or, you can click button to open an existing project file.

8. After you finish the design, click to save the project file.

POWERING DOWN THE BOARD BETWEEN PROGRAMMING OPERATIONS

Disconnect the USB cable from the DC1427A/DC1613A before removing or inserting a LTC3884 into the program-ming socket.

WHAT YOU CAN DO WITH THE DC2298A

1. Compare the contents of the EEPROM in the LTC3884UK against your project or hex file.

2. Reprogram the contents of the EEPORM in the LTC3884UK using your project or hex File.

3. Verify the EEPROM within the DC2298A contains the factory defaults.

a. From the LTpowerPlay interface, load the factory defaults project file. This file is located at:

C:\Program Files\Linear Technology\LTpowerPlay\project files\ltc3884\datasheet_defaults.proj

b. Click the Verify button.
