Connect the USB-TO-GPIO adapter to your PC using the supplied USB cable. Connect the

TPS6236xEVM connector J8 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.

Connect the load (processor) to either the output headers J4 and J6 (for currents below 1A) or to the

output terminal block J7 (for currents greater than 1A). The leads should be short and twisted.

Connect the SNS+ and SNS- signals from header J5 to the load. For proper regulation, these must be

connected to the output.

Install jumpers, JP1 through JP4 to the desired positions. Jumper JP1 must be across pins 1 and 2 for the

TPS6236x to operate.

Connect at least a 3 A rated input power supply, set to provide between 2.5V and 5.5V, between J1 and

J3. The leads should be short and twisted. Turn on the power supply.
