Setup
Connect the USB-TO-GPIO adapter to your PC using the supplied USB cable. Connect the
TPS650380EVM connector J19 or J25 to the USB-TO-GPIO adapter using the supplied 10-pin ribbon
cable. The connectors on the ribbon cable are keyed to prevent incorrect installation. Only install a USB-
TO-GPIO adaptor in either J19 or J25 at the same time.
Connect the load (processor) to either the output headers J4 and J6, J7 and J9 (for currents below 1A),
and J10 and J12 or to the output terminal blocks J17 and J18 (for currents greater than 1A). The leads
should be short and twisted.
Install jumpers, JP1 through JP2 to the desired positions. Jumper JP1 must be across pins 1 and 2 for the
TPS650380 to operate.
Connect at least a 5 A rated input power supply, set to provide between 2.5 V and 5.5 V, between J1 and
J3 (for currents below 1 A) or to the terminal block J16 (for currents greater than 1 A). The leads should
be short and twisted. Turn on the power supply.
