DEMO MANUAL DC1508B LTC2974/LTC2975/LTC2977/ LTC2978/LTC2978A Programming Board for PMBus Power System Managers Description The DC1508B programming board contains the circuitry needed to program and verify the EEPROM of the LTC2974, LTC2975, LTC2977, LTC2978, and LTC2978A. This is its sole purpose. The DC1508B is shipped with a clamshell style programming socket installed. The EEPROM contains the factory default configuration. The LTpowerPlay™ *.proj file that corresponds to the factory default can be found in the GUI. To properly program and verify the contents of the EEPROM, download and install the LTpowerPlay software (GUI). http://www.linear.com/ltpowerplay/ You also need a Linear Technology DC1613 USB to SMBus/PMBus Controller.

DC1508B Top Side Details (DC1508B-A Shown) Order Information There are two versions of the DC1508B. Each version of the programming board comes with only one socket. See Table 1. Table 1. Order Number Supported Devices DC1508B-A LTC2977, LTC2978, LTC2978A DC1508B-B LTC2974, LTC2975 LTpowerPlay GUI Software LTpowerPlay is a powerful Windows-based development environment that supports Linear Technology Power System Management ICs with EEPROM. The software supports a variety of different tasks. You can use LTpowerPlay to evaluate Linear Technology ICs by connecting to a demo board system. LTpowerPlay can also be used in an offline mode (with no hardware present) in order to build a multichip configuration file that can be saved and reloaded at a later time. LTpowerPlay provides unprecedented diagnostic and debug features. It becomes a valuable diagnostic tool during board bring-up to program or tweak the power management scheme in a system or to diagnose power issues when bringing up rails. LTpowerPlay utilizes the DC1613 I2C/SMBus/PMBus Controller to communicate with one of many potential targets, including the DC1508B programming board or a customer board. dc1508bf 2 DEMO MANUAL DC1508B LTpowerPlay GUI Software The software also provides an automatic update feature to keep the software current with the latest set of device drivers and documentation.

Screenshot of the LTpowerPlay GUI dc1508bf 3 DEMO MANUAL DC1508B Quick Start Procedure The DC1508B programming board makes it easy to program and verify the EEPROM contents of the device. 1.Place jumpers and switches in the following default positions. WP: OFF ASEL1: L ASEL0: L S1: OFF 4.Close lid. It will snap into place. See Figure 5. NOTE: Removal and insertion of the IC should be done with either tweezers or a vacuum suction device, and also with the power switch S1 set to OFF. NOTE: By default, the ASEL jumpers are both set to low. If you wish to program a device with an offset address other than 0x5C, adjust the ASEL jumpers appropriately. Consult device data sheet for details. 2.Connect the DC1613 controller to your PC. Plug the ribbon cable into connector J1 of the DC1508B programming board. 3.Open the socket lid. Place the IC inside with pin 1 located in the upper left corner. See Figure 4. Figure 5. DC1613 Ribbon Cable Attached and Lid Closed 5.Set the power switch S1 to the ON position. The VDD33 LED will illuminate, indicating the on-chip regulator is providing internal power. 6.Launch the LTpowerPlay software from your PC. Select Utilities>Programming Utility from the menu. Click “…” next to the selection box and select a .proj file to program the device. Figure 4. Open Clamshell Lid dc1508bf 4 DEMO MANUAL DC1508B Quick Start Procedure 7.LTpowerPlay is ready to program/verify the device. a. Click the Program and Verify button, and wait for the process to complete. 8.Prior to removing the device and programming another, power must be removed from the device. Set the power switch S1 to the OFF position. Open the socket lid. Remove the device with tweezers or a vacuum tool. The USB ribbon cable may remain connected to the programming board. 9.To program another device, repeat Steps 3 through 5, then Steps 7 and 8. LTpowerPlay’s Programming Utility does not need to be closed. b.After the process is complete, you will see Successfully Programmed and Verified Device in the status bar at the bottom. dc1508bf 5 DEMO MANUAL DC1508B Parts List ITEM QTY REFERENCE PART DESCRIPTION MANUFACTURER/PART NUMBER Required Circuit Components 1 1 U1 (DC1508B-A) or U2 (DC1508B-B) IC SOCKET, SPRING LOADED, 64-QFN PLASTRONICS: 64QN50S19090-A 2 3 C1, C2, C7 CAP CER 1µF 16V 10% X7R 0603 MURATA: GRM188R71C105KA12D 3 8 C3, C4, C5, C6, C8, C9, C10, C11 CAP CER 0.1µF 16V 10% X7R 0603 MURATA: GRM188R71C104KA01D 4 1 J1 CONN HEADER 12POS 2mm STR DL PCB FCI: 98414-G06-12ULF 5 1 JP1 CONN HEADER 0.100 INCH 1X3POS WÜRTH: 613 003 111 21 6 2 JP2, JP3 CONN HEADER 0.100 INCH 1X4POS WÜRTH: 613 004 111 21 7 1 LED1 LED GREEN HIGH BRIGHT ESS SMD PANASONIC: LNJ326W83RA 8 4 MH1, MH2, MH3, MH4 STAND-OFF NYLON 1/4" SNAP IN WÜRTH: 702 931 000 9 5 R1, R2, R4, R7, R8 RES 10.0k 1/10W 1% 0603 SMD YAGEO: RC0603FR-0710KL 10 1 R3 RES 1.3k 1/10W 1% 0603 SMD YAGEO: RC0603JR-071K3L 11 0 R5, R6 (OPTIONAL) RES 10.0k 1/10W 1% 0603 SMD 12 3 SH1, SH2, SH3 CONN SHUNT 0.1IN 2POS BLACK WÜRTH: 609 002 134 21 13 1 S1 SW SLIDE DPDT 6VDC 0.3A PCMNT C&K: JS202011CQN 14 4 TP1, TP2, TP3, TP4 TERM SOLDER TURRET 0.219" 0.078"L MILL-MAX: 2501-2-00-80-00-00-07-0 15 1 U3 2k I2C SERIAL EEPROM MICROCHIP TECHNOLOGY: 24AA02T-I/OT dc1508bf 6 1 2 3 Information furnished by Linear Technology Corporation is believed to be accurate and reliable.
