This section describes how to properly use the TPS62175EVM-098.

2.1 Input/Output Connector Descriptions

J1 – VIN Positive input connection from the input supply for the EVM.

J2 – S+/S- Input voltage sense connections. Measure the input voltage at this point.

J3 – GND Return connection from the input supply for the EVM.

J4 – VOUT Output voltage connection.

J5 – S+/S- Output voltage sense connections. Measure the output voltage at this point.

J6 – GND Output return connection.

J7 – PG/GND The PG output appears on pin 1 of this header with a convenient ground on pin 2.

JP1 – EN EN pin input jumper. Place the supplied jumper across ON and EN to turn on the IC.

Place the jumper across OFF and EN to turn off the IC.

JP2 – SLEEP SLEEP pin input jumper. Place the supplied jumper across ON and SLEEP to activate

SLEEP mode. Place the jumper across OFF and SLEEP to activate normal mode.

JP3 – PG PG pin pullup voltage jumper. Place the supplied jumper on JP3 to connect the PG pin

Pullup Voltage pullup resistor to Vout. Alternatively, the jumper can be removed and a different

voltage can be supplied on pin 1 to pull up the PG pin to a different level. This

externally applied voltage must remain below 7 V.
