This chapter describes the jumpers and connectors on the EVM, as well as how to properly connect, set
up, and use the TPS60255EVM-262.
up, and use the TPS60255EVM-262.
J1 – VIN
This is the positive input voltage connection to the converter. The EVM operates from any supply voltage
between 2.7 V and 6 V. The leads to the input supply should be twisted and kept as short as possible to
minimize EMI transmission and input voltage droop.

J2 – GND
This is the input return connection for the input power supply.
J3 – USB to GPIO Connector
This is the connector for the interface box. Connect the ribbon cable of the interface box to this device.
J4 – VLED ANODE
This is the anode connection when using external WLEDs. The cathode for external WLEDs can be
connected to the appropriate side of jumper JP1-JP7. This connection can also be used to measure the
voltage and/or voltage ripple at the VOUT pin of the device.

J5 – AUX
This is the cathode connection when using external WLEDs connected to Group C.
JP1 – DA1
JP1 is used to connect the cathode of the DA1 LED to the GA1 pin on the TPS60255. Place a shunt on
JP1 to connect the WLED to the GA1 input pin. Remove the shunt and place an ammeter in series to
measure the DA1 current or attach an external WLED using this jumper.
