DEMO MANUAL DC2450A LTC2936 Programming Board for Programmable Hex Voltage Supervisor with EEPROM Description The DC2450A programming board contains the circuitry needed to program and verify the EEPROM of the LTC®2936. This is its sole purpose. The LTC2936 comes in either a 24-pin SSOP or a 24-pin QFN package. The DC2450A-A supports the QFN and the DC2450A-B supports the SSOP package. The LTpowerPlay™ GUI stores configuration settings into the LTC2936 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 features an offline mode to build a multi-chip configuration file for later use with hardware. LTpowerPlay provides unprecedented system level 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 SYSTEM TREE OF ALL DEVICES CONFIGURATION SETTING FOR ALL DEVICES IN SYSTEM TREE 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 DC2450A demo system or a customer board. 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 dc2450af 3 DEMO MANUAL DC2450A Quick Start Procedure The DC2450A programming board makes it easy to program and verify the LTC2936 EEPROM contents. 1. Place jumpers and switches in the following default positions: ASEL1: L ASEL0: L OFF S1: 3. If using DC2450A-B, open the pinch contacts of the socket by pressing down and holding the top of the spring loaded socket frame. Place the IC inside the socket with pin 1 located in the upper left corner. Slowly release the top of socket frame, allowing contacts to pinch together and grip IC leads. See Figure 5. NOTE: By default, the ASEL jumpers are both set to low. If you wish to program a device with an address other than 0x50, adjust the ASEL jumpers appropriately. Consult device data sheet for details. 2. Connect the DC1613 USB controller to your PC. Plug the ribbon cable into connector J1 of the DC2450A programming board. See Figure 4. Figure 5. DC2450A-B and IC Installed Figure 4. DC2450A-B with Open Socket NOTE: Removal and insertion of the IC should be done with either tweezers or a vacuum device, and also with the power switch S1 set to OFF. 4 dc2450af DEMO MANUAL DC2450A Quick Start Procedure 4. If using DC2450A-A, flip open the socket lid and place the IC inside with pin 1 located in the upper left corner. See Figure 6. 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. The device programming utility shown in Figure 8 should pop up automatically. If it does not then select the Utilities>Programming Utility from the menu shown in Figure 9. PIN 1 INDICATOR 7. Click “…” next to the selection box and select a .proj file from your system to program the device. See Figure 8. DC2450 F06 Figure 6. DC2450A-A and IC Installed Figure 8. Selecting a .proj File to Program Close the lid. It will snap into place. See Figure 7. Figure 9. Utilities > Programming Utility from the Menu Figure 7. DC2450A-A and IC Installed dc2450af 5 DEMO MANUAL DC2450A Quick Start Procedure 8. Click the “Program and Verify” button (see Figure 10) and wait for the process to complete. After the process is complete, you will see “Successfully Programmed and Verified Device”, in the status bar at the bottom. See Figure 11. Figure 11. Programmed and Verified Device 9. Set the power switch S1 to the OFF position prior to removing the device. Figure 10. Device Programming Utility. 6 Repeat steps above to program additional devices. LTpowerPlay’s Programming Utility does not need to be closed. The ribbon cable may remain connected to the programming board. dc2450af Information furnished by Linear Technology Corporation is believed to be accurate and reliable.
