Page 5: Test Setup
The LP5891Q1EVM can be powered either by the TMS320F280039C LaunchPad with the USB power (when the current consumption is low) or an external power supply (the LP5891Q1EVM and the TMS320F280039C LaunchPad are powered separately). Single LP5891Q1EVM can be quickly set up and tested by following these steps: 1. - Page 6 1. Download the code to the TMS320F280039C LaunchPad with TI Code Composer Studio software. 2. For the first LP5891Q1EVM, put the J5 jumper on TP1 5V and EX 5V. Then put the J6 jumper on EX5V and the middle. Set the switch S1 towards SOUT1TO2. These setups are marked with red boxes on the First...
