Si825x Multi-Phase POL-RD
9. Restoring Factory Defaults
The Si825x Multi-Phase POL Reference Design includes hex files created for the multi-phase POL application.
Downloading these hex files to the Si8250 Multi-Phase POL Target Board will restore the board to its factory
defaults.
9.1. Restoring the Si8250
To download the factory default Si8250 hex file to the target board, perform the following steps:
1. Connect the USB Debug Adaptor’s ribbon cable to the Si8250 Multi-Phase POL Target Board at J7 as shown in
2. Open the IDE by selecting Silicon Laboratories→Silicon Laboratories IDE from the PC programs menu.
3. The Si8250 Multi-Phase POL Target Board has several connection requirements that need to be specified
4. Click the Connect button in the toolbar or select Debug→Connect from the menu to connect to the device.
5. Select Debug→Download Object File... from the IDE menus to open the download window.
6. Press the Browse button to open the Download Filename... window.
7. In the List files of type: drop down box, select the Intel-Hex option.
8. Browse to the “SiLabs\Power\Reference_Designs\Multi_Phase_POL\Firmware\multi_phase_POL\hex”
9. Press the Download button to download the file.
10.Click the Disconnect button in the toolbar, or select Debug→Disconnect from the menu to disconnect from
