DEMO MANUAL DC2347A LTC2937 Programming Board DESCRIPTION Demo System Hardware Required The DC2347A contains only those functions necessary to safely program and verify the LTC2937 configuration EEPROM. It serves no other purpose. The DC2347A holds the LTC2937 in a clamshell socket for convenient access and replacement of parts. The LTpowerPlay™ GUI software, running on a PC, provides a simple interface to program and verify the EEPROM with a user supplied configuration. Demo System Software Required What Can You Do with The DC2347A • LTpowerPlay (GUI) • Program the contents of the EEPROM with your project or HEX file. The LTpowerPlay software can be downloaded from: • Verify the contents of the EEPROM against your project or HEX file. To access technical support documents for LTC Power System Management Products visit "Help -> View Online Help" in the LTpowerPlay menu. • Verify the contents of the EEPROM against factory defaults. • Microsoft Windows PC • DC1613 USB to I2C/SMBus/PMBus Controller • DC2347A Programming Board http://www.linear.com/ltpowerplay Design files for this circuit board are available at http://www.linear.com/demo/DC2347A L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and LTpowerPlay is a trademark of Linear Technology Corporation.

Download and install the LTpowerPlay GUI: http://www.linear.com/ltpowerplay 2. Remove the DC2347A board from the ESD protective bag and place it on a level surface. Connect the DC1613 I2C/SMBus/PMBus Controller to the DC2347A board using the 12-pin ribbon cable. Set the jumpers ASEL1, ASEL2, and ASEL3 for the desired device I2C address. Note that each project file contains a fixed device address, which must match the ASEL jumper settings on the board. See the LTC2937 data sheet for a discussion of device addressing. Set the WP jumper to OFF. Set the POWER switch to OFF. 3. Connect the USB-to-I2C/SMBus/PMBus Controller to a USB port on your PC. 4. Insert an LTC2937 part into the clamshell socket and verify that it is upright and not upside-down in the socket. Close the lid; it will snap shut. Only remove and replace ICs in the socket when the POWER switch is OFF. 5. Apply power to the device by sliding the POWER switch to ON. When the part receives power it powers-up its 3.3V VDD pin, and LED1 will illuminate green. If no part is installed in the socket, or if the part is up-side down, the LED will not illuminate, and programming is not possible. 7. If the Programming Utility does not launch automatically, select LTpowerPlay→Utilities→Programming Utility from the menu. 8. Click “…” and select a project file to program the device. Ensure that the ASEL jumpers match the device address in the project file. 9. Click “Program and Verify System” to program the device. Upon success, the status bar at the bottom will turn from yellow to green and indicate “Successfully Programmed and Verified System!” 10.After programming the LTC2937, set the POWER switch to OFF and remove the part from the socket. Repeat steps 4 to 9 with additional LTC2937 parts as necessary. 6. Launch the LTpowerPlay GUI. The GUI automatically identifies the DC2347A and launches the appropriate interface protocol. dc2347af 3 DEMO MANUAL DC2347A PARTS LIST ITEM QTY REFERENCE PART DESCRIPTION MANUFACTURER/PART NUMBER Required Circuit Components 1 3 C4, C12 CAP, CER, 100nF, X5R, 16V, 10%, 0603 MURATA, GRM188R61C104KA01D 2 1 C13 CAP, CER, 2.2µF, X5R, 16V, 10%, 0603 MURATA, GRM188R61C225KE15D 3 1 C1 CAP, CER, 1µF, X5R, 16V, 10%, 0603 MURATA, GRM188R61C105KA93D 4 1 R3 RES, 1.3k, 1/10W, 1%, 0603 VISHAY, CRCW06031K30FKEA 5 5 R1, R2, R5, R6, R7 RES, 10k, 1/16W, 1%, 0603 VISHAY, CRCW060310K0FKED 6 9 R4, R8, R9, R10, R11, R12, R13, R14, R15 RES, 0.0Ω, 1/10W, 0603 VISHAY, CRCW06030000Z0EA 7 1 LED1 LED, GREEN, 0603 PANASONIC, LNJ326W83RA 8 4 TP1, TP2, TP3, TP4 TEST POINT TURRET, 0.094" MILL-MAX, 2501-2-00-80-00-00-07-0 9 3 ASEL1, ASEL2, ASEL3 CONN, HEADER, 1x4, 0.1" SULLINS, PRPC004SAAN-RC 10 1 WP CONN, HEADER, 1x3, 0.1" SULLINS, PRPC003SAAN-RC 11 4 WP, ASEL1, ASEL2, ASEL3 SHUNT JUMPER, 0.1" 3M, 969002-0000-DA 12 1 J1 CONN, HEADER, 2x6, 2MM FCI, 98414-G06-12ULF 13 1 U4 IC SERIAL EEPROM, SOT-23-5 MICROCHIP, 24AA02T-I/OT 14 1 U1 SOCKET, CLAMSHELL, QFN PLASTRONICS, 28QN50S16050-A 15 1 S1 SW SLIDE DPDT 6VDC 0.3A PCMNT C&K COMPONENTS, JS202011CQN 16 4 STANDOFF, NYLON, SNAP-ON, 0.25" TALL KEYSTONE, 8831 4 dc2347af DEMO MANUAL DC2347A 4 3 5 2 1 22 21 20 19 18 17 16 15 WP SHARE_CLK SPCLK SCL SDA RSTB FAULTB ALERTB V1 V2 V3 V4 V5 V6 28 27 26 25 24 23 1 2 3 4 5 6 7 8 9 10 11 12 EN1 EN2 EN3 EN4 EN5 EN6 9 10 11 12 13 14 MARGB VPWR VDD GND ON ASEL1 ASEL2 ASEL3 PAD PAD 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 5 6 7 8 1/23/2015 2:12:30 PM f=0.60 C:\Users\nenger\Documents\LTC2937\DC2347A-PROGRAMMING-BOARD\EAGLE\DC2347A-Programming.sch (Sheet: 1/1) 3 6 1 2 5 1 2 3 4 SCHEMATIC DIAGRAM dc2347af Information furnished by Linear Technology Corporation is believed to be accurate and reliable.
