Hardware Setup
Configure JP1, JP2, JP3, and JP4 using a shorting block. These jumpers are used to connect the SDA
and SCL lines of the I
2
C interface to a pullup resistor to the input voltage. The USB interface adapter
supplied with the EVM has its own internal pullup resistors; therefore, no additional pullup is required. No
jumper is necessary if the Texas Instruments USB interface adapter is used to communicate with the
TPS62350EVM board, and JP1 and JP2 should be left open.
Configure the jumper on JP3 to the desired setting. Shorting between VSEL and HIGH (pins 1 and 2)
makes the TPS62350 power up with the output voltage set by the VSEL1 register. Shorting between
VSEL and LOW (pins 2 and 3) makes the TPS62350 power up with the output voltage set by the VSEL0
register.
Configure JP4 as desired. Shorting between EN and ON (pins 1 and 2) enables the TPS62350. Shorting
between EN and OFF (pins 2 and 3) disables the TPS62350.
Connect the USB interface adapter to your PC using the supplied USB cable. Connect the TPS62350EVM
board to the USB interface adapter using the supplied 10-pin ribbon cable. The connectors on the ribbon
cable are keyed to prevent incorrect installation.
Connect an input voltage supply to the TPS62350EVM board. The TPS62350 uses an input voltage
between 2.7 V and 6 V. Connect the positive input voltage to J1. Connect the input voltage return (ground)
connection to J2.
