2 Setup
This section describes how to correctly use the TPS62442EVM-122.
2.1 Connector Descriptions
J1, Pin 1 and 2 – VIN Positive input voltage connection from the input supply for the EVM
J1, Pin 3 and 4 – S+/S– Input voltage sense connections. Measure the input voltage at this point.
J1, Pin 5 and 6 – GND Input return connection from the input supply for the EVM
J2, Pin 1 and 2 – VOUT Converter 1 positive output voltage connection
J2, Pin 3 and 4 – S+/S– Converter 1 output voltage sense connections. Measure the output voltage at this point.
J2, Pin 5 and 6 – GND Converter 1 output return connection
J3, Pin 1 and 2 – VOUT Converter 2 positive output voltage connection
J3, Pin 3 and 4 – S+/S– Converter 2 output voltage sense connections. Measure the output voltage at this point.
J3, Pin 5 and 6 – GND Converter 2 output return connection
JP1 – EN1 EN1 pin jumper. Place the supplied jumper across ON and EN to turn on the IC converter 1. Place
the jumper across OFF and EN to turn off the IC.
JP2 – EN2 EN2 pin jumper. Place the supplied jumper across ON and EN to turn on the IC converter 2. Place
the jumper across OFF and EN to turn off the IC.
JP3 – MODE/SYNC MODE/SYNC pin jumper. Place the supplied jumper across VIN and MODE/SYNC to force the
device in fixed frequency PWM operation at all load currents. Place the jumper across MODE/SYNC
and GND to enable power save mode. Connect a clock signal to MODE/SYNC referenced to GND to
synchronize the switching frequency to the clock signal.
J4 – PG1 The PG1 output appears on pin 1 of this header with a convenient ground on pin 2 for converter 1.
J5 – PG2 The PG2 output appears on pin 1 of this header with a convenient ground on pin 2 for converter 2.
2.2 Hardware Setup
To operate the EVM, set jumpers JP1, JP2, and JP3 to the desired positions per Section 2.1 . Connect the input
supply to J1 between VIN and GND. Connect the load to J2 between VOUT1 and GND and Connect the load to
J3 between VOUT2 and GND.
