DEMO MANUAL DC1709A LTC3880EUJ Programming Board for Dual-/ Two-Phase DC/DC Controller with Digital Power Management Description LTC3880 FEATURES Demonstration circuit 1709A contains the circuitry needed to program and verify the EEPROM within the LTC®3880 and LTC3880-1. That is its only purpose. The DC1709A is shipped with a LTC3880 installed in the clamshell style programming socket. The EEPROM contains the factory default configuration. The LTpowerPlay™ .proj file that corresponds to the factory default can be found in the GUI. n n ±0.5% output voltage accuracy over temperature In order to properly verify the contents of the EEPROM, download and install the LTpowerPlay software (GUI). The software can be downloaded from: n Integrated 16-bit ADC n Internal EEPROM and fault logging n Integrated powerful N-channel MOSFET gate drivers n Wide VIN range: 4.5V to 24V n VOUT range: 0.5V to 5.5V n Supports power-up into prebiased load n Analog current mode control loop n Accurate PolyPhase® current sharing n Available in a 40-pin (6mm × 6mm) QFN package http://www.linear.com/ltpowerplay You also need a Linear Technology USB to I2C/SMBus/ PMBus Controller, DC1613A or DC1427A. DEMO SYSTEM REQUIRED HARDWARE n n n Windows PC I2C/SMBus/PMBus USB to DC1427A Controller, DC1613A or n Telemetry readback includes VIN, IIN, VOUT, IOUT, temperature and faults Programmable voltage, current limit, digital soft-start/ stop, sequencing, margining, OV/UV and frequency synchronization (250kHz to 1MHz) Design files for this circuit board are available at http://www.linear.com/demo DC1709A DEMO SYSTEM REQUIRED SOFTWARE n n PMBus/I2C compliant serial interface L, LT, LTC, LTM, Linear Technology, the Linear logo and PolyPhase are registered trademarks and LTpowerPlay is a trademark of Linear Technology Corporation.

LTC3880 Programming Setup Using the DC1709A DC1709af 1 DEMO MANUAL DC1709A Quick Start Procedure Demonstration circuit 1709A makes it easy to program and verify the EEPROM contents of the LTC3880. 1. Make sure jumpers are in the following positions: JUMPER POSITION FUNCTION JP1 Off Write Protection of LTC3880 JP2 On Write Protection of Identification EEPROM 6. On your PC, launch LTpowerPlay. LTpowerPlay will identify the DC1709A and launch the appropriate GUI (see Figure 5). NOTE: You will see an undertemperature (UT) fault. This is normal since the temperature sensing pin is grounded. Ignore this fault at the moment. 2. Open the lid of the socket, SKT1. Verify there is an IC inside (see Figure 2). 7. Change the GUI parameters according to your system requirements. Or, you can open an existing project file by clicking this button: 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. 8. After you finish the design, save the project file by clicking this button: 4. Plug one end of the USB cable to your PC. Plug the other end of the USB cable into the I2C/SMBus/PMBus controller. 5. If you have a DC1427A, plug the ribbon cable into J1 (see Figure 3). If you have a DC1613A, plug the ribbon cable into J2, as shown in Figure 3 and Figure 4. POWERING DOWN THE BOARD BETWEEN PROGRAMMING OPERATIONS Disconnect the USB cable from the DC1427A/DC1613A before removing or inserting a LTC3880 into the programming socket. Figure 2. Open Shell.

DC1613A Ribbon Cable Installation DC1709af 3 DEMO MANUAL DC1709A Quick Start Procedure WHAT YOU CAN DO WITH THE DC1709A 1. Compare the contents of the EEPROM in the LTC3880 against your project or hex file. 3. Verify the EEPROM within the DC1709A contains the factory defaults. n 2. Reprogram the contents of the EEPROM in the LTC3880 using your project or hex file. From the LTpowerPlay interface, load the factory defaults project file. This file is located at: C:\Program Files\Linear Technology\LTpowerPlay\ project files\democricuits\LTC3880_datasheet_ defaults.proj n Click the Verify button.
